Born | 1956 (age 67–68) Rochester, Minnesota, U.S. |
Education | University of Kansas (BA) University of Iowa (PhD) |

J. Ann Selzer is an American political pollster who is the president of the Des Moines, Iowa-based polling firm Selzer & Company, which she founded in 1996.[1][2] Her polls of Iowa voters have a reputation for being highly accurate, based on their performance in elections from 2008 through 2020.[3][4] She was described as "the best pollster in politics" by Clare Malone of FiveThirtyEight, which also gives Selzer & Company a rare A+ grade for accuracy.[2][5]
Early life and education
Selzer was born in Rochester, Minnesota, in 1956, the middle child in a family of five.[6] She was raised in Topeka, Kansas. Selzer attended the University of Kansas, initially as a pre-med student, but eventually lost interest in medicine.[5] She graduated with a Bachelor of Arts in Speech and Dramatics Arts in 1978.[7] She then earned a Ph.D. in Communication Theory and Research from the University of Iowa in 1984.[8]
Career
After graduate school, Selzer worked for The Des Moines Register. She established her own polling firm, Selzer & Company, in 1996. She has worked as the pollster for the Des Moines Register for many years, and has overseen nearly all of the Register's Iowa Polls since 1987, according to FiveThirtyEight. She has also done polling work for numerous other news organizations, including the Detroit Free Press and the Indianapolis Star.[9][5] Recently, Selzer has partnered with Grinnell College as a part of the Grinnell College National Poll program.[10]
Selzer was the only pollster to correctly predict Barack Obama's comfortable victory in the 2008 Iowa Democratic caucuses,[9] and her poll of the 2014 United States Senate election in Iowa also mirrored the actual result exceptionally closely.[11]
Selzer & Co. conducted their final 2016 presidential poll in Iowa in early November, showing Donald Trump ahead of Hillary Clinton by seven percentage points.[12] Most other polls at the time showed a much closer race.[13] Trump won Iowa by 9.4 percentage points. Selzer's final Iowa poll ahead of the 2020 presidential election showed Trump ahead of Joe Biden by seven percentage points, and Republican Senator Joni Ernst ahead of Democratic challenger Theresa Greenfield by four percentage points.[14] This was the only poll conducted in fall 2020 to show Trump ahead by more than two points, while Ernst's race was considered a toss-up.[15][16] Trump won Iowa by 8.2 percentage points, while Ernst was re-elected by 6.6 points. In a post-election interview with Bloomberg, Selzer suggested that her polls' consistently high performance may be related to making fewer assumptions about the electorate, and said, "I assumed nothing. My data told me."[17]
Prior to the 2024 United States presidential election, Selzer & Co. released their final Iowa poll that had Kamala Harris leading Trump 47% to 44% in the state, markedly different from other polls that showed Trump with a significant lead.[18] Trump criticized the accuracy of the poll. Selzer responded by saying the poll used the same methodology as in 2016 and 2020, and that, "It would not be in my best interest, or that of my clients—The Des Moines Register and Mediacom—to conjure fake numbers."[19] Contrary to the poll, Trump won Iowa.[20][21]
