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.

The Associated Press declared President-elect Donald Trump the winner in Arizona on Saturday night after vote updates in Maricopa and other counties added to his overall lead, putting the state out of reach for Vice President Kamala Harris.
