Kari Lake Launches Arizona Senate Bid, Bringing Combative Trump Loyalty to Competitive 2024 Race

Kari Lake, former GOP candidate for Arizona governor, announced her campaign for U.S. Senate at a rally with Trump's endorsement.
Lake continues to deny her gubernatorial election loss and promises to fight for election integrity if elected to the Senate.
Lake will compete in the Republican primary, while Rep. Ruben Gallego is the Democratic frontrunner to replace Sen. Kyrsten Sinema.
Polls show a tight hypothetical three-way race between Lake, Gallego, and potential independent Sinema.
Lake's combative persona concerns some Republicans but appeals to loyal Trump supporters in Arizona.
