It took nearly a week of staring at spreadsheets and waiting for the desert mail-in ballots to trickle through the machines, but we finally have the answer to who won the Arizona senate. Ruben Gallego, a Marine combat veteran and five-term congressman, officially clinched the seat. He beat out Republican Kari Lake in a race that was frankly much tighter than most of the summer polling suggested it would be.
If you were watching the returns on election night, things looked a little hazy. Arizona is notorious for its slow count—mostly because everyone there loves voting by mail—but the Associated Press finally called it on November 12, 2024. Gallego pulled in about 50.1% of the vote, while Lake trailed with 47.7%.
This wasn't just another win for the Democrats. It was a massive moment for the state. Gallego is now Arizona’s first-ever Latino U.S. Senator. He’s taking over the seat vacated by Kyrsten Sinema, the independent who basically set the political world on fire when she left the Democratic party a while back.
The Numbers Don't Lie: How the Map Broke
The final tally saw Gallego winning by roughly 80,000 votes. In a state that Donald Trump won by roughly 185,000 votes, that’s a pretty wild gap. Basically, a huge chunk of Arizonans walked into the booth, checked the box for Trump, and then immediately checked the box for Gallego.

Why did that happen? Ticket-splitting.
It’s a phenomenon that's becoming rarer in American politics, but in Arizona, it’s alive and well. Gallego managed to run about seven points ahead of Kamala Harris in the state. He didn’t just win the hardcore progressive base in Tempe or downtown Phoenix; he managed to keep the margins close enough in Maricopa County and snag enough "McCain Republicans" to cross the finish line.
Key Demographics That Flipped the Script
- The Latino Vote: Exit polls showed Gallego winning about 60% of Hispanic voters. Harris, for comparison, was closer to 54%.
- The Veteran Connection: Being an Iraq War veteran isn’t just a line on his resume. Gallego leaned into his Marine background hard, which likely helped him in more conservative areas like Pinal County.
- The Suburban Shift: Women in the suburbs were a huge factor. Reproductive rights were on the ballot (literally, with Proposition 139), and Gallego tied himself to that issue while painting Lake as too extreme.
Why Kari Lake Couldn't Close the Gap
Kari Lake is a household name in Arizona. You’ve probably seen her on the news for decades as an anchor. But that name recognition turned out to be a double-edged sword. While she has a very loyal base, she struggled to win over the middle.

Honestly, her biggest hurdle might have been her history with the "Old Guard" of the Arizona GOP. She famously told McCain Republicans to "get the hell out" during her 2022 gubernatorial run, and it seems many of them took her advice. Even with Donald Trump’s endorsement and his own victory in the state, Lake couldn't capture that same magic.
What This Means for the 119th Congress
With the Arizona race settled, the Senate map is officially locked in. Republicans still have the majority—53 seats to 47—but Gallego's win prevented them from having a total blowout.
Gallego is joining Mark Kelly, making Arizona a state with two Democratic senators for the first time in a very long time. It’s a huge shift for a place that used to be the land of Barry Goldwater.

What Gallego is Planning to do First
In his victory speech, he kept it pretty focused. He talked about "fixing the broken immigration system"—a huge deal in a border state—and protecting veterans' benefits. He also made a point to say he’d represent the people who didn't vote for him. Classic move, but in a state as divided as Arizona, it’s probably a necessary one.
The reality is that who won the Arizona senate tells us more about the state's identity than just a party label. Arizona isn't "blue," and it isn't "red." It’s a weird, fiercely independent purple that values personal story and military service over pure partisan loyalty.
Actionable Steps for Arizona Voters
If you’re wondering what happens next now that the dust has settled, keep an eye on these milestones:
- Watch the Committee Assignments: As a veteran, Gallego is likely gunning for a spot on the Armed Services Committee. His influence there will dictate how much federal funding flows into Arizona's military bases.
- Track the 2026 Registration Drive: The DNC just launched a massive registration push in Arizona because they know the registration gap is actually widening in favor of Republicans. If you want to be involved, now is the time to check your status.
- Monitor the Border Legislation: With a Republican president and a split-ish Senate, the "pragmatic" brand Gallego sold during the campaign will be put to the test immediately. See if he actually votes with the "Majority Democrats" group he helped found.
The 2024 cycle is over, but the work in the desert is just getting started.
