Arizona live election results for the 2024 presidential election

Democratic Rep. Ruben Gallego and Republican Kari Lake are facing off for the seat currently held by Sen. Kyrsten Sinema, who is an independent but caucuses with Democrats. The seat is key for Democrats to hold on to control of the Senate or for Republicans to take control.

Gallego, a progressive lawmaker and former Marine, has been leading in the polls leading up to Election Day.

Late. Kyrsten Sinema, a former Democrat turned independent and long a boogeyman for liberals, is retiring this year, and Democratic Rep. Rueben Gallego faces Republican Kari Lake in a race for the open seat. Gallego, who represents Phoenix and the surrounding western suburbs in Congress, has a fundraising advantage, having raised nearly $22 million through the end of September, while Lake has nearly $17 million.

A polarizing ally of Trump, Lake first ran for governor in 2022 and refused to accept the election results. ONE CBS News poll conducted from October 11-16, Gallego led Lake with 9 points.

ONE CBS News poll conducted from October 11-16 in Arizona, Trump had a 3-point lead over Harris. Trump is boosted by voters who say immigration/borders and the economy are their top issues, while Harris has advantages with voters who prioritize abortion rights and the state of democracy which keeps this race close.

Arizona polls close at 7:00 PM MT (9:00 PM ET).
