Is McCarthy ever going to give up and say "maybe I shouldn't be speaker"?

nope

They'll have to pry his corpse off the podium

To quote Tim Curry as Cardinal Richeleau, “That. Can be. Arranged!”

He had already moved his stuff into the speaker's office before the first vote.

And then Matt "18 Is Too Old For Me" Gaetz sent a letter to the Office of Congressional Ethics asking if he need to move out.

I heard about the office thing, and thought it textbook chutzpah.
