PHOENIX — Kari Lake won the Republican Senate primary in Arizona, NBC News projects, officially setting up a critical matchup against Democratic Rep. Ruben Gallego.
Lake, a staunch ally of former President Donald Trump, was ahead of Pinal County Sheriff Mark Lamb 53% to 41% with roughly 77% of the expected vote in. Former news anchor Elizabeth Reye was running in a distant third.
Lake advances to the general election for the seat being vacated by Sen. Krysten Synema, I-Ariz, against Gallego, a Phoenix-area congressman and Marine veteran who ran unopposed in the Democratic primary. The race in battleground Arizona will be among a handful that determine partisan control of the Senate this fall.
Lake, a 54-year-old former newscaster, first emerged on the political scene during her unsuccessful run for governor in 2022 as a prominent promoter of Trump’s false claims that the 2020 election was stolen. She later refused to accept her own loss to Democrat Katie Hobbs, who is now Arizona’s governor.
Lake has heavily touted the former president’s endorsement again during her Senate campaign. She arrived to her polling location in Paradise Valley, Ariz., on Tuesday in a new tour bus that featured a giant decal of her with the former president and the words “Endorsed by President Trump.”
“Knowing that I’m Trump-endorsed is important to a lot of people here in Arizona,” Lake said.
Lake’s challenge will now be taking her MAGA-themed message to a broader electorate in a critical swing state for both the race for the White House and control of the Senate. Democrats currently hold a 51-49 majority in the upper chamber.
The 44-year-old Gallego, once a member of the Congressional Progressive Caucus, has played up his willingness to work across the aisle as he seeks statewide office.
“In the 554 days since we launched this campaign, Arizonans in every corner of the state have made clear that they want a U.S. Senator who can bring people together to defend abortion rights, cut costs for families, protect our water future, and take care of our veterans — and that’s exactly what I intend to do,” Gallego said in a statement Tuesday night.
Gallego enters the general election stage of the race with a cash advantage: He had $8.2 million in his campaign account compared to $2.1 million for Lake as of July 10.
Arizona also hosted some notable House primaries on Tuesday.
Freshman GOP Rep. Juan Ciscomani fended off a primary challenger in the swing 6th District, setting up a rematch with Former state Sen. Kirsten Engel, a Democrat.
Engel, who ran uncontested in Tuesday’s Democratic primary, lost two years earlier to Ciscomani by less than two percentage points. The race for the seat — which covers a large chunk of the southeastern part of the state, including Tucson — is considered a toss-up by the Cook Political Report with Amy Walter.
