Elections in Arizona |

![]() |
The 2024 United States Senate election in Arizona was held on November 5, 2024, to elect a member of the United States Senate to represent the state of Arizona. This election was the fifth consecutive even-number year in which a Senate election was held in Arizona after 2016, 2018, 2020, and 2022. Democratic U.S. Representative Ruben Gallego defeated Republican former news journalist Kari Lake to succeed Democrat-turned-independent incumbent Kyrsten Sinema, who did not seek a second term.[1]
Sinema, who was elected as a Democrat, was considered vulnerable to a primary challenge due to frequently opposing her party's legislative agenda. After preparing a re-election bid as an independent, Sinema announced she would retire from the Senate.[2][1] Lake, the Republican nominee in the 2022 Arizona gubernatorial election, won her party's nomination with 55% of the vote against Pinal County sheriff Mark Lamb. The election was considered among the most competitive Senate races in 2024.[3]
Most polls and ratings had Gallego as the slight favorite to win.[4][5] Gallego defeated Lake by 2.4 percentage points, a closer race than polls had projected for most of the campaign. Republican presidential candidate Donald Trump's wider-than-expected victory in the state likely contributed to this, but there was also a significant amount of ticket splitting for Gallego and Trump. Gallego outperformed Kamala Harris by the 4th largest margin among Democratic senate candidates in 2024. This election marked the fourth consecutive election cycle in which Democrats won a Senate election in Arizona.
Specifically, Gallego received about 93,000 more votes than Kamala Harris, while Lake received about 175,000 fewer votes than Donald Trump.
This was the first time that Arizona voted for candidates of different political parties for U.S. senator and president since Democrat Dennis DeConcini was reelected as Republican George H. W. Bush carried the state in 1988. Gallego also became the first Latino elected to the Senate from Arizona, a state with a large Latino population [6]
