Maybe that's the endgame. Put the R-senators on the ropes to vote for impeachment. Their constituents vote them out, or don't vote at all. Boom, they're rid of Trump AND have the house and senate back.
How do the dumbass GOP senators benefit who vote that way? Cushy beltway job is not enough, they’ll be beholden to a Rat. First Rat worthless son-in-law, niece, etc that comes along that needs s job out they go! Nothing beats the power & perks of office - NOTHING!, particularly office when a majority!
