the alternative would be to let him stay in office and lose the next election to him also, because he is going to get reelected
regardless of how stupid of a fukk I think he is, I don't see him losing. They need to get his ass up out of there and they should have done it a long time ago. If you say this is the first time he's done something actionable, I'll take your word for it
You didn't answer the question of how you expect them to get him out of office when Republicans control the Senate.
