Mr. McGuire just became a state senator as of Jan. 2024. He’s already trying to climb from state to federal, based on Mr. Good’s “disloyalty” to Trump for supporting DeSantis. McGuire supported keeping McCarthy, whereas Good supported getting rid of him.
I’m not sure what McGuire did to support McCarthy. The article doesn’t specify. It just says it was a point of contention.
