“This is their best chance to put a stake through Donald Trump’s political future,” she said. “If they don’t take it, Donald Trump is going to control this party for the next 10 years.”

Under Trump’s influence, Longwell warned, the GOP will become the party of the QAnon conspiracy theory-supporting Reps. Marjorie Taylor Greene (R-Ga.) and Lauren Boebert (R-Colo.).

It’s “not just dangerous for the Republican Party,” she cautioned, but “an existential threat to the country to have one of the two major political parties controlled by people who are out there spreading conspiracy theories.”

“And I’m not talking about Marjorie Taylor Greene,” Longwell clarified. “I’m talking about (House GOP Minority Leader) Kevin McCarthy and (Florida GOP Rep.) Matt Gaetz and so many others in Congress who voted to object to a free and fair election, who told voters that it was stolen from them, who followed Donald Trump and it led to a violent attack on the Capitol.”
