2024 United States presidential election in Iowa

The 2024 United States presidential election in Iowa is scheduled to take place on Tuesday, November 5, 2024, as part of the 2024 United States elections in which all 50 states plus the District of Columbia will participate. Iowa voters will choose electors to represent them in the Electoral College via a popular vote. The state of Iowa has six electoral votes in the Electoral College, following reapportionment due to the 2020 United States census in which the state neither gained nor lost a seat.

An Upper Midwestern state, although Iowa was considered both a swing and a bellwether state for decades, it voted significantly more Republican than the nation-at-large in both 2016 and 2020 and is now considered a moderately red state at the federal and state levels. As a result, it is not expected to be seriously contested by the Democrats in 2024 as Republican Donald Trump won the state by a somewhat comfortable margin while losing nationally in the latter election, despite polls indicating a close race.

Furthermore, during the 2022 midterms, all three statewide incumbent Republicans (governor, secretary of agriculture, and secretary of state) won reelection by more than 18%, two of three statewide incumbent Democrats (28-year incumbent attorney general and 40-year incumbent treasurer) lost to Republican challengers, and the remaining incumbent Democrat (4-year incumbent auditor) won by less than 3,000 votes and 0.23%. Republicans also won all four of Iowa's U.S. House seats. As such, Iowa is widely predicted to remain red in 2024.

In April 2023, incumbent Democratic president Joe Biden officially announced a re-election campaign for 2024.

Attorney Robert F. Kennedy Jr. has gathered enough signatures to appear on the ballot, as he announced in April.

Democratic caucuses
During the Iowa Democratic caucuses, in-person caucusing focusing only on party business was held on January 15, but voting on candidates will be done exclusively via mail-in ballots from January 12 until Super Tuesday, March 5, 2024. This was the result of a compromise between the Iowa Democratic Party and the Democratic National Committee (DNC). Iowa traditionally holds its race first during the presidential primary and caucuses season, but the DNC originally wanted South Carolina to instead hold its race first on February 3.

Republican caucuses
The Iowa Republican caucuses were held on January 15, 2024, the first-in-the-nation nomination contest of the 2024 Republican primaries. Former president Donald Trump won the primary with the largest margin of victory for a non-incumbent in the Iowa caucuses. Trump's overwhelming victory in the state established his position early as the frontrunner.
