The2024 United States presidential election in Iowa was held on Tuesday, November 5, 2024, as part of the2024 United States presidential election in which all 50 states plus theDistrict of Columbia participated.Iowa voters chose electors to represent them in theElectoral College via a popular vote. The state of Iowa has six electoral votes in the Electoral College, followingreapportionment due to the2020 United States census in which the state neither gained nor lost a seat.[1]
For most of the race, Iowa was expected to be a safe red state.[2] A poll performed bySelzer and Co. and published byThe Des Moines Register on November 2 claimed Harris to be up by 3%, leading some to predict a far closer race than initially expected. Nonetheless, Democrats did not seriously contest the state.[3][4][5]
In the election, Donald Trump won the state in a landslide, winning the state by 13.2 percentage points, the widest margin for any candidate since1972. This was the first time a Republican won the state by double digits since1980.[6][7] Selzer retired from polling following the election.[8][9]
During the Iowa Democratic caucuses, in-person caucusing focusing only on party business was held on January 15. Voting on candidates was done exclusively viamail-in ballots from January 12 untilSuper Tuesday, March 5, 2024. This was the result of a compromise between theIowa Democratic Party and theDemocratic National Committee (DNC). Iowa traditionally holds its race first during thepresidential primary and caucuses season, but the DNC originally wanted South Carolina to instead hold its race first on February 3.[10]
