Now Kent, a former Green Beret who criticized Beutler for her impeachment vote and who has shared conspiracy theories about voting, will lose to businesswoman Marie Gluesenkamp Perez, a Democrat.
"If Beutler had been the Republican nominee, she'd have won with 60% of the vote by now," said Chris Vance, the former chairman of the Washington State Republican Party, in an interview before NBC News projected the race.
GOP primaries, Vance said, are no longer electing the best candidates because the base is more interested in ties to Trump.
"If you're a Republican elected official, you've got to keep your head down," said Vance, who left the party after Trump's election.
Gluesenkamp Perez avoided talking about party politics while emphasizing her rural background and her family's long ties to Washington state.
