So I saw the GOP is trying to get Trump to drop out of the Presidential race. A few things
1) It's a slap in the face to those who selected him in the Primary
2) It's a slap in the face to those who voted for him in early voting
3) It's too late to take him off the balot
4) Who would they get? Pence? Sorry you can't change the election 1 month before. If it was September that's one thing.
Try in 2020 and hope you can hang on to the Senate.
