A review of the 2024 results show that Trump flipped or expanded his lead in several crucial counties. Arizona's most populous county Maricopa, which includes Phoenix, shifted decisively back to Trump, who, with 89 percent of votes counted, is leading by 4 points over Kamala Harris. Biden won Maricopa by 2 points in 2020.

The victory added to the list of battleground states that Mr. Trump lost in 2020 and flipped back four years later.

Donald Trump won the battleground state of Arizona, completing a sweep of all seven swing states in this year’s election. Arizona, which holds 11 Electoral College votes, had been trending blue in recent years, with many statewide jobs held by Democrats, but the former president brought it back to Republicans.
