The 2024 United States presidential election in Arizona took place on Tuesday, November 5, 2024, as part of the 2024 United States presidential election in which all 50 states plus the District of Columbia participated. Arizona voters chose electors to represent them in the Electoral College via a popular vote. The state of Arizona has 11 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.[1] Arizona was considered a crucial swing state in 2024.
The Republican nominee was former president Donald Trump.[2] Formerly a moderately red state in the American Southwest, Trump won Arizona in 2016 by 3.5%, a major drop in margin of Republican victory in the traditional GOP stronghold compared to previous cycles, despite an overall more favorable year for Republicans than the previous two presidential elections. Biden narrowly won in Arizona in 2020 by 0.3%. Due to the diversification of Maricopa County, a traditionally Republican stronghold that holds 61.6% of the state's population, the state is now considered a purple state.[3][4]Robert F. Kennedy Jr. had gathered enough signatures to appear on the ballot, but his petition was eventually withdrawn.[5][6]
Arizona was the final state to be called in the election, with Donald Trump winning by 5.5%, surpassing the margins predicted by most polls.[7] This was the largest margin of victory since 2012 for a Republican presidential candidate, as well as the first time since 2012 that a presidential candidate won the state with an absolute majority of the vote. It was Trump's largest margin of victory in the seven swing states he won, and Trump's strongest performance in a state won by Biden in 2020.
