Mere rhetoric, if well-written. Nobody in either party has ever resigned over just doing a horrible job or pissing off a bunch of writers, only over things that involve criminal charges, a humiliation of some sort in their private life that tubes their chances for re-election, or some dread faux pas that matters only in their own closed little circle. Especially not Representatives who have a bunch of people who don't even vote in their districts upset with them and writing bombastic articles about it which almost nobody who does vote in their districts will ever read.
