The '''2012 United States Senate elections''' were held on November 6, 2012, with 33 of the 100 seats in the [[United States Senate|Senate]], all [[Classes of United States senators|Class 1]] seats, being contested in regular elections whose winners would serve 6-year terms beginning January 3, 2013, with the [[113th United States Congress#Members|113th Congress]]. [[Democratic Party (United States)|Democrats]] had 21 seats up for election, plus 1 [[Independent (United States)|Independent]], and 1 [[Independent Democrat]], while the [[Republican Party (United States)|Republicans]] only had 10 seats up for election. The presidential election, [[2012 United States House of Representatives elections|elections to the House of Representatives]], [[2012 United States gubernatorial elections|elections for governors in 14 states and territories]], and many state and local elections were also held on the same day.

The Democrats gained Republican-held seats in [[2012 United States Senate election in Massachusetts|Massachusetts]] and [[2012 United States Senate election in Indiana|Indiana]] and one from an Independent Democrat in [[2012 United States Senate election in Connecticut|Connecticut]], leaving them with a total of 53 seats. Additionally, they held open seats in [[2012 United States Senate election in Hawaii|Hawaii]], [[2012 United States Senate election in New Mexico|New Mexico]], [[2012 United States Senate election in North Dakota|North Dakota]], [[2012 United States Senate election in Virginia|Virginia]], and [[2012 United States Senate election in Wisconsin|Wisconsin]]. The Republicans, despite losing 2 of their seats, picked an open seat in [[2012 United States Senate election in Nebraska|Nebraska]] up and retained open seats in [[2012 United States Senate election in Arizona|Arizona]] and [[2012 United States Senate election in Texas|Texas]], ending with a total of 45 seats. The Independents retained a seat in [[2012 United States Senate election in Vermont|Vermont]] and gained an additional seat from the Republicans in [[2012 United States Senate election in Maine|Maine]], bringing their total to 2 seats. Both Independents would caucus with the Democrats, forming a majority caucus with a combined total of 55 seats.

{{As of|2023}}, this was the last time the Democrats won seats in [[2012 United States Senate election in Florida|Florida]], Indiana, [[2012 United States Senate election in Missouri|Missouri]], and North Dakota; and at least one seat in a state that was lost by the Democratic candidate in the [[2012 United States presidential election|concurrent presidential election]]. It was also the last time the Republican Party won a seat in [[2012 United States Senate election in Nevada|Nevada]]. The Democrats would not win control of the Senate again until [[2020 United States Senate elections|2020]]{{efn|After the 2020 elections, the Senate was split 50-50 and a Democratic vice president was elected [[List of tie-breaking votes cast by the vice president of the United States|to break ties]], giving Democrats a technical majority in the Senate.}} and would not win an outright majority again until [[2022 United States Senate elections|2022]]. This is also the last time a Democrat flipped a Senate seat in a state that they lost in the concurrent presidential election.

Additionally, this was the first time since [[1936 United States Senate elections|1936]] that a 2-term Democratic presidential candidate had Senate coattails on both occasions. (Although Franklin Roosevelt won third and fourth terms in 1940 and 1944, respectively, he lost Senate seats on both occasions.) This was also the first time since [[1964 United States Senate elections|1964]] in which either party had to defend more than two-thirds of the Senate seats up for grabs but managed to make net gains.<ref>{{Cite news|url=https://www.nytimes.com/2012/11/07/us/politics/senate-races.html?pagewanted=all|title=Democrats Keep Control of the Senate|first=Jonathan |last=Weisman|newspaper=The New York Times|date=November 6, 2012}}</ref><ref>{{Cite news|url=https://www.wsj.com/articles/SB10001424052970203347104578101441741711334|title=Democrats Retain Control of U.S. Senate|first=Naftali|last=Bendavid|newspaper=The Wall Street Journal|date=November 6, 2012}}</ref> {{As of|2023}}, this is the last election cycle in which an incumbent senator lost renomination, the last election cycle in which there were no runoff elections, the last time a party flipped a Senate seat while failing to carry the state in the presidential election, and the last time a party flipped a Senate seat in a state whose other seat was flipped by the opposition party in the previous election cycle.

== Final pre-election predictions ==
The table below gives an overview of some final predictions of the November general elections by several well-known institutes and people. While there were very few mistakes (predictions in the wrong direction; essentially only Montana and North Dakota, by both Sabato's Crystal Ball and FiveThirtyEight), FiveThirtyEight and Princeton Election Consortium had 2-4 races in the Lean categories and no tossups, whereas all other sources had at least eleven races in the middle three categories, and in particular many Tossup races.

Incumbent Democrat [[Dianne Feinstein]] was re-elected.  The primary election on June 5 took place under California's new blanket primary, where all candidates appear on the same ballot, regardless of party. In the primary, voters voted for any candidate listed, or write-in any other candidate. The top two finishers — regardless of party — advanced to the general election in November, even if a candidate managed to receive a majority of the votes cast in the June primary. In the primary, less than 15% of the total 2010 census population voted. Incumbent Democrat [[Dianne Feinstein]] finished first in the blanket primary with 49.5% of the vote. The second-place finisher was Republican candidate and autism activist Elizabeth Emken, who won 12.7% of the vote.

He also said that during the last debate he had with McMahon, "I thought she was embarrassingly clueless" and that "I think she is a terrible candidate and I think she would make a terrible senator."

From a long way out Nelson appeared to be vulnerable, with some earlier polls showing Mack leading. However, in the last few weeks with new polls conducted it appeared as though Nelson was headed for a victory. The last poll place him 5 percentage points ahead of Mack. In fact Nelson would win easily by 13 percentage points. Nelson performed well in Southeast Florida (the Miami area), [[Tampa]], [[Gainesville, Florida|Gainesville]], typically Democratic areas. Nelson however managed to win in areas that lean Republican. For example, Nelson won in [[Duval County, Florida|Duval County]] home of [[Jacksonville]], and [[Volusia County]] home of [[Daytona Beach]]. Nelson's ability to outperform President Obama led to him winning the Election easily. President Obama would still win [[Florida]], but by just about 74,000 votes, and less than a percentage point. Nelson began his third term in the Senate on January 3, 2013.

Mourdock became embroiled in a controversy after stating that [[pregnancy from rape]] is "something that God intended". His remarks were made during a debate on October 23, 2012, while explaining his opposition to [[abortion]] even in the case of [[rape]]. At the debate Mourdock, when asked what his position on abortion was, responded:
<blockquote>"I know there are some who disagree and I respect their point of view but I believe that life begins at conception. The only exception I have to have an abortion is in that case of the life of the mother. I just struggled with it myself for a long time but I came to realize: "Life is that gift from God that I think even if life begins in that horrible situation of rape, that it is something that God intended to happen."<ref name="Raju">{{Cite web |last=Raju |first=Manu |title=Richard Mourdock under fire for rape remarks |website=[[Politico]] |date=October 23, 2012 |url=http://www.politico.com/blogs/on-congress/2012/10/richard-mourdock-under-fire-for-rape-remarks-139411.html?hp=l1 |access-date=October 24, 2012}}</ref></blockquote>

Despite initially being in the race early on and poised to easily win, popular Republican [[Olympia Snowe]] suddenly retired instead of running for re-election to a fourth term. Former Independent Governor [[Angus King]] won the open seat. Following senator [[Joe Lieberman]]'s retirement from the Senate in 2013, King became the second Independent incumbent senator, after [[Vermont]]'s [[Bernie Sanders]].

Incumbent [[Olympia Snowe]] won re-election to a third term in 2006 with 74.01% of the vote over Democrat Jean Hay Bright and independent Bill Slavick. Due to the unpopularity of some of Snowe's votes among conservative voters, namely for the [[American Recovery and Reinvestment Act of 2009]] and initial support of the [[Patient Protection and Affordable Care Act]], there was speculation that she would face competition in the 2012 Republican primary from more conservative challengers.<ref>{{Cite web |url=http://www.politico.com/news/stories/1110/44963.html |title=GOP senators see threat on right |date=November 10, 2010 |access-date=November 20, 2010 |work=[[Politico (newspaper)|Politico]] |first=Shira |last=Toeplitz}}</ref> The [[Tea Party Express]] had promised to aid in a primary against Snowe.<ref>{{Cite news |url=http://www.rollcall.com/news/-203309-1.html |title=Tea Party Express Names Snowe as Its Next Moderate Republican Target |first=Steve |last=Peoples |work=Roll Call |date=February 10, 2011 |access-date=February 11, 2011}}</ref> There had also been speculation that Snowe would switch parties, though she has always denied this.<ref>{{Cite web |url=http://www.theatlanticwire.com/politics/2010/11/will-olympia-snowe-switch-parties/22328/ |title=Will Olympia Snowe Switch Parties? |date=November 10, 2010 |access-date=April 15, 2010 |work=The Atlantic Journal |first=Ray |last=Gustini |archive-date=April 24, 2011 |archive-url=https://web.archive.org/web/20110424101908/http://www.theatlanticwire.com/politics/2010/11/will-olympia-snowe-switch-parties/22328/ |url-status=dead }}</ref><ref>{{Cite web |url=https://thehill.com/opinion/columnists/markos-moulitas/70072-right-time-for-snowe-switch/ |title=Right time for Snowe switch |date=September 14, 2010 |access-date=April 15, 2010 |work=The Hill |first=Markos |last=Moulitsas}}</ref><ref>{{Cite news |url=http://voices.washingtonpost.com/ezra-klein/2009/11/will_olympia_snowe_switch_part.html |archive-url=https://web.archive.org/web/20121014234403/http://voices.washingtonpost.com/ezra-klein/2009/11/will_olympia_snowe_switch_part.html |url-status=dead |archive-date=October 14, 2012 |title=Will Olympia Snowe switch parties? |date=November 11, 2009 |access-date=April 15, 2010 |newspaper=The Washington Post |first=Ezra |last=Klein}}</ref> By June 2011, Snowe had officially entered her name with signatures to run in the Republican primary, saying, she "would never switch parties".

Incumbent Republican [[Scott Brown (politician)|Scott Brown]] ran for re-election to a first full term. He had been elected in a [[2010 United States Senate special election in Massachusetts|special election in 2010]] following the death of incumbent Democrat [[Ted Kennedy]]. Brown faced no challengers from his own party. For the Democrats, an initial wide field of prospective candidates narrowed after the entry of [[Harvard Law School]] Professor [[Elizabeth Warren]], the architect of the [[Consumer Financial Protection Bureau]]. Warren clinched near-unanimous party support, with all but one of the other Democratic candidates withdrawing following her entrance. After winning her party's nomination, eliminating any need for a primary, she faced Brown in the general election.

The election was one of the most-followed races in 2012 and cost approximately $82 million, which made it the most expensive election in Massachusetts history and the second-most expensive in the entire [[2012 United States elections|2012 election cycle]], next to [[2012 United States presidential election|that year's presidential election]]. This was despite the two candidates' having agreed not to allow [[Political action committee|outside money]] to influence the race. Opinion polling indicated a close race for much of the campaign, though Warren opened up a small but consistent lead in the final few weeks. She went on to defeat Brown by over 236,000 votes, 54% to 46%.

Despite President Obama's winning the state easily, and winning all of the state's counties, this race was fairly close. As expected, Warren performed very well in [[Suffolk County, Massachusetts|Suffolk County]], which is home to the state's largest city and its capital [[Boston]].

Incumbent Democrat [[Claire McCaskill]] was unopposed in her primary and U.S. Representative [[Todd Akin]] won the Republican nomination with a plurality in a close three-way race. McCaskill was re-elected to a second term.

''[[Time (magazine)|Time]]'' featured the race in their Senate article. Similar to other races, the article mentioned how McCaskill was fading in pre-election polls, and she was considered the most vulnerable/endangered Democratic incumbent that year. But Akin's comments about a woman's body preventing pregnancy if it was "legitimate rape" quickly shot McCaskill back up, winning her the election.<ref>{{Citation |title=The Senate – Much Fury, Little Change |page=18 |magazine=[[Time (magazine)|Time]] |date=November 19, 2012}}</ref><ref>{{Cite news |last=Hughes |first=Siobhan |title=Claire McCaskill Defeats Todd Akin to Win Missouri Senate Seat |url=https://blogs.wsj.com/washwire/2012/11/06/mccaskill-defeats-akin-to-win-missouri-senate-seat/ |newspaper=The Wall Street Journal |date=November 6, 2012}}</ref><ref>{{Cite news |last=Eligon |first=John |title=Turnaround in Missouri as Incumbent Keeps Seat |url=https://www.nytimes.com/2012/11/07/us/politics/turnaround-in-missouri-as-incumbent-keeps-seat.html |newspaper=The New York Times |date=November 7, 2012}}</ref>

While making remarks on [[rape]] and [[abortion]] on August 19, 2012, Akin made the claim that women victims of what he described as "legitimate rape" rarely experience [[pregnancy from rape]]. In an interview aired on St. Louis television station [[KTVI-TV]], Aiken was asked his views on whether women who became pregnant due to [[rape]] should have the option of [[Abortion in the United States|abortion]]. He replied:

<blockquote>Well you know, people always want to try to make that as one of those things, well how do you, how do you slice this particularly tough sort of ethical question. First of all, from what I understand from doctors, that's really rare. If it's a legitimate rape, the female body has ways to try to shut that whole thing down.
But let's assume that maybe that didn't work or something. I think there should be some punishment, but the punishment ought to be on the rapist and not attacking the child.<ref>{{Cite web |last=Jaco |first=Charles |title=Jaco Report: Full Interview With Todd Akin |date=August 19, 2012 |url=http://fox2now.com/2012/08/19/the-jaco-report-august-19-2012/ |work=Fox News |access-date=August 20, 2012 |archive-date=June 6, 2017 |archive-url=https://web.archive.org/web/20170606230441/http://fox2now.com/2012/08/19/the-jaco-report-august-19-2012/ |url-status=dead }}</ref></blockquote>

The comments from Akin almost immediately led to uproar, with the term "legitimate rape" being taken to imply belief in a [[Rape#Victim blaming, secondary victimization and other mistreatment|view that some kinds of rape are "legitimate"]], or alternatively that the many victims who do become [[Pregnancy from rape|pregnant from rape]] are likely to be [[False accusation of rape|lying about their claim]]. His claims about the likelihood of pregnancy resulting from rape were widely seen as being based on long-discredited [[pseudoscience]] with experts seeing the claims as lacking any basis of medical validity.<ref name="canard">{{Cite news |title=A Canard That Will Not Die: 'Legitimate Rape' Doesn't Cause Pregnancy |date=August 19, 2012 |url=https://www.theatlantic.com/politics/archive/2012/08/a-canard-that-will-not-die-legitimate-rape-doesn't-cause-pregnancy/261303/ |work=The Atlantic |access-date=August 21, 2012 }} {{Dead link|date=April 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref name="pseudo">{{Cite web |first=David A. |last=Graham |url=https://www.theatlantic.com/politics/archive/2012/08/video-of-the-day-forcible-rape-and-paul-ryans-akin-problem/261460/ |title=Video of the Day: 'Forcible Rape' and Paul Ryan's Akin Problem |work=The Atlantic |date=August 22, 2012 |access-date=August 25, 2012}}</ref><ref name="NYT-21-08-2012">{{Cite news |title=Health Experts Dismiss Assertions on Rape |date=August 21, 2012 |url=https://www.nytimes.com/2012/08/21/us/politics/rape-assertions-are-dismissed-by-health-experts.html |work=The New York Times |access-date=August 21, 2012 |first=Pam |last=Belluck}}</ref> Akin was not the first to make such claims, but was perhaps one of the most prominent.<ref name="Freind">{{Cite news |last=Kliff |first=Sarah |url=https://www.washingtonpost.com/blogs/ezra-klein/wp/2012/08/20/rep-todd-akin-is-wrong-about-rape-and-pregnancy-but-hes-not-alone/ |title=Rep.

On October 20, at a fundraiser, Akin compared McCaskill to a dog.

Even though the last poll before the election showed Akin only losing by four percentage points, McCaskill defeated him handily, by a 15.5% margin of victory and a vote margin of 420,985. Both McCaskill and incumbent governor Jay Nixon, running at the same time, were able to get a large number of votes from rural parts of the state, something President [[Barack Obama]] was not able to do. McCaskill and Nixon were declared the winners of their respective races even before the known big Democratic strongholds of [[St. Louis]] and [[Kansas City]] came in. Akin conceded defeat to McCaskill at 10:38 P.M. Central Time.

Incumbent Republican [[Dean Heller]], who was recently appointed to this seat left vacant by resigning U.S. senator [[John Ensign]], was narrowly elected to his first full term over Congresswoman [[Shelley Berkley]].

Incumbent Democrat [[Kirsten Gillibrand]] won re-election to her first full term. Gillibrand was opposed in the general election by [[Wendy Long]] (who ran on the Republican and Conservative Party tickets) and by three minor party candidates. Gillibrand was re-elected with 72% of the vote, by a margin of 46%, the highest margin for any statewide candidate in New York. Gillibrand performed 9 points better than President [[Barack Obama]] did in the presidential race in New York. She carried 60 out of 62 counties statewide. There was one debate, held in October 2012 where Gillibrand and Long debated various issues such as the economy, abortion rights, the debt and deficit, foreign policy, jobs, and tax and regulatory policy.

[[Governor of New York|Governor]] [[David Paterson]] appointed then-[[United States House of Representatives|U.S. Representative]] [[Kirsten Gillibrand]] to serve as U.S. senator from New York until the [[2010 United States Senate special election in New York|2010 special election]], succeeding former U.S. senator [[Hillary Clinton]], who resigned to serve as [[U.S. Secretary of State]] in the [[Barack Obama administration|Obama administration]]. Gillibrand won the [[2010 United States Senate special election in New York|special election in 2010]] with 62.95% of the vote over former U.S. Representative [[Joseph DioGuardi]].

According to preliminary results, Gillibrand won re-election by a landslide of over 70% of the vote on November 6, 2012.

In 2006, U.S. Representative [[Sherrod Brown]] had defeated two-term incumbent Republican [[Mike DeWine]] 56%-44% [[2006 United States Senate election in Ohio|2006 election]]. Over the past six years, he established a very liberal, progressive, and populist record. The ''[[National Journal]]'' named Brown the most liberal U.S. senator in the past two years.<ref>{{Cite news| url=http://www.huffingtonpost.com/2011/12/22/sherrod-brown_n_1162819.html |work=Huffington Post |first=Amanda |last=Terkel |title=Which Senate Race Is Attracting Most GOP Third-Party Spending? |date=December 22, 2011}}</ref> ''[[The Washington Post]]'' called him a "modern-day [[Paul Wellstone]]."

Mandel, 34, was elected state treasurer in 2010. Before that, he was a Lyndhurst City Councilman and Ohio State Representative. He was criticized as Ohio Treasurer for not fulfilling his pledge to serve a four-year term and for not attending any of the Board of Deposit monthly meetings.<ref>{{Cite news| url=http://www.huffingtonpost.com/2012/02/24/josh-mandel-ohio-treasurer-senate-candidate-board-of-deposit-meetings_n_1299379.html |work=Huffington Post |first=Michael |last=McAuliff |title=Ohio Senate Candidate Skipped Board Meetings For No Known Reason |date=February 24, 2012}}</ref> However, Mandel raised a lot of money. He was called a rising star in the [[Republican Party (United States)|Republican Party]] and was called "the rock star of the party." He was also compared to [[Marco Rubio]].<ref>[https://www.theatlantic.com/politics/archive/2012/03/is-josh-mandel-the-next-marco-rubio/253956/ Politics – Molly Ball – Is Josh Mandel the Next Marco Rubio? – The Atlantic<!-- Bot generated title -->]</ref>

Mandel's campaign was singled out by the independent [[fact-checking]] group [[Politifact]] for its "casual relationship with the truth" and its tendency to "double down" after inaccuracies were pointed out. The fact-checking group wrote: "For all the gifts Mandel has, from his compelling personal narrative as an Iraq war veteran to a well-oiled fundraising machine, whoppers are fast becoming a calling card of his candidacy."<ref name="politifact-age">{{Cite web |publisher=[[Politifact]] |title=Even in an age of fact checking, the whopper lives |first=Henry |last=Gomez |url=http://www.politifact.com/ohio/article/2012/mar/26/even-age-fact-checking-whopper-lives/ |date=March 26, 2012 |access-date=July 5, 2012}}</ref>

Mandel raised $7.2 million through the first quarter of 2012.

The group was funded by anonymous donors and run by lobbyist Tom Norris of [[Columbus, Ohio]]-based Cap Square Solutions.<ref>{{Cite news |first=Justin |last=Elliot |title=Revealed: The Dark Money Group Attacking Sen.

Brown did better than polls right before the election suggested. Instead of winning by two points (which polls right before the election had suggested) Brown won by six points. Republicans could not come back from the huge margins for the Democrats of [[Cuyahoga County]], [[Franklin County, Ohio|Franklin County]], [[Lucas County, Ohio|Lucas County]], and [[Hamilton County, Ohio|Hamilton County]].

Incumbent Democrat [[Bob Casey, Jr.]] won re-election to a second term, defeating Republican nominee [[Tom Smith (Pennsylvania)|Tom Smith]], and [[Libertarian Party (United States)|Libertarian]] nominee Rayburn Smith.

The primary elections occurred on April 24, 2012, during which the Republicans and Democrats selected nominees for the [[general election]]. The Republican primary was a five-way contest. Tom Smith, the eventual nominee, faced [[David A. Christian]], [[Sam Rohrer]], Marc Scaringi, and [[Steve Welch]]. The Democratic primary was not heavily contested. Incumbent Bob Casey, Jr., defeated Joseph Vodvarka by a wide margin. The Libertarian Party nominated Rayburn Smith.

Casey led most pre-election polls and eventually defeated his opponents to win re-election to a second term in the U.S. Senate. In so doing, Casey became the first Democratic senator from Pennsylvania elected to a second term [[1962 United States Senate election in Pennsylvania|in 50 years]].

Pennsylvania was considered a [[Swing state|battleground state]]; since the [[1970 Pennsylvania gubernatorial election|1970]] election of Governor [[Milton Shapp]], partisan control of the governorship had alternated between Democratic and Republican. Additionally, Republicans had controlled the [[Pennsylvania Senate|State Senate]] since 1995, while Democrats assumed control of the [[Pennsylvania House of Representatives|State House]] following the [[2006 Pennsylvania House of Representatives elections|2006 election]], only to lose control in the [[2010 Pennsylvania House of Representatives elections|2010 election]], though the Democrats had won the state in every presidential election from [[1992 United States presidential election|1992]] to [[2012 United States presidential election|2012]].

Despite many predictions of a close race, the election was not close. Casey, the incumbent, despite being seen as somewhat vulnerable, went into election night with most analysts thinking he would win. Casey would win by more than expected. This can be traced to several factors. Casey trounced Smith in [[Philadelphia County]] home of [[Philadelphia]]. Casey also won the surrounding collar counties of, Bucks, Chester, Delaware, and Montgomery, which are seen as vital in statewide elections in [[Pennsylvania]]. Casey also performed well in [[Allegheny County, Pennsylvania|Allegheny County]] home of [[Pittsburgh]]. Casey also performed well in Erie. Casey also performed strongly in the [[Scranton]] area. Smith did well in rural counties, but it wasn't enough to overcome the lead Casey had built in the huge population centers. Casey was sworn in for his second term beginning at noon on January 3, 2013.

Incumbent Democrat [[Joe Manchin]] won re-election to a first full term.

[[Robert Byrd]] held this seat in the U.S. Senate since 1959, after having served in the House of Representatives since 1953, making him the longest-serving person in Congress. Byrd [[Party leaders of the United States Senate|led his party in the Senate]] from 1977 to 1989, as Majority Leader or Minority Leader. Afterward, as the most senior Democrat in the Senate, he served as [[President pro tempore of the United States Senate|President pro tempore of the Senate]] whenever his party was in the majority, including at the time of his death. After Byrd's death, West Virginia Secretary of State [[Natalie Tennant]] initially announced that a [[List of special elections to the United States Senate|special election]] would be held the same day as the regular election for the six-year term. However, that special election was rescheduled to 2010 for it to coincide with the 2010 mid-term elections. Governor [[Joe Manchin]] made a temporary appointment of [[Carte Goodwin]] to the vacant seat. Goodwin was later replaced by Manchin who won [[2010 United States Senate special election in West Virginia|the 2010 special election]].

Raese filed a rematch against Manchin, arguing that he now had more material to criticize Manchin for.

Raese wrote an op-ed in the [[Charleston Gazette]] saying about Manchin, "Yes, he'll talk like a conservative and act like he's fiscally responsible to appeal to more moderate voters, but under that outward appearance of a lovable rube is the heart of a tax-and-spend liberal."<ref name="autogeneratedWV"/>

Raese continued to make controversial statements. In April 2012, he equated smoking bans with [[Adolf Hitler]]'s [[yellow badge]]. He said "in Monongalia County now, I have to put a huge sticker on my buildings to say this is a smoke-free environment. This is brought to you by the government of Monongalia County. Okay?

Incumbent Democrat [[Herb Kohl]] retired instead of running for re-election to a fifth term.  Democratic Congresswoman [[Tammy Baldwin]] of [[Wisconsin's 2nd congressional district]] ran unopposed for her party's nomination. The Republican nominee was former [[Governor of Wisconsin]] and former [[United States Secretary of Health and Human Services|Secretary of Health and Human Services]] [[Tommy Thompson]], who won with a plurality in a four-way race. In the general election, Baldwin defeated Thompson and won the open seat. She became the first woman elected to represent Wisconsin in the Senate and the first openly [[Homosexuality|gay]] U.S. senator in history. This is also the first time Thompson lost a statewide race.
