PHOENIX — Kari Lake won the Republican nomination for U.S. Senate in Arizona on Tuesday, setting up a fierce battle against Democratic U.S. Rep. Ruben Gallego for a seat that could be crucial to deciding Senate control.
In Maricopa County, which includes metro Phoenix and 60% of Arizona's voters, Republicans also were choosing between a slate of incumbents who have stood up to former President Donald Trump's lies about the 2020 election and challengers who claim it was stolen.
The primary will give insights about where the narrowly divided state is headed going into the final sprint of the 2024 election, when Arizona is central to the fight for control of the White House and Congress.
Gallego ran unopposed in the Democratic primary for Senate.
Accepting victory Tuesday night, Lake called Trump a ''hero'' and urged his supporters to back her as well.
''He can't do this alone,'' Lake said. ''He needs backup in Washington, D.C. And I'm going to be his backup.''
The once-crowded field of Republicans looking at the Senate race thinned out when Lake, who built a national profile in Trump's ''Make America Great Again'' movement in an unsuccessful 2022 bid for Arizona governor, made clear she planned to run for the seat.
Lake defeated Pinal County Sheriff Mark Lamb, who had contended he is more electable and the best candidate to secure the border. But he struggled to raise the money needed to make his case to voters. Through the end of June, Lake had raised $10.3 million compared with Lamb's $2 million.
