Madison Cawthorn has said a lot of stupid shit over his short career in Congress, but it appears that his cocaine sex orgy story from last weekend was the final straw for fellow Republicans, as CNN reports Republican North Carolina Senator Thom Tillis is backing a primary challenge to Cawthorn from state Senator Chuck Edwards. “It comes down to focus on the district, producing results for the district, and in my opinion, Mr. Cawthorn hasn’t demonstrated much in the way of results over the last 18 months,” Tillis told CNN on Wednesday. Tillis isn’t alone in the “establishment” purge of an “America First” patriot, as North Carolina state Senate leader Phil Berger and state House speaker Tim Moore, are headlining a fundraiser for Edwards on Thursday.
