Paul Ryan tried that once before and got his azz handed to him. You don’t offer VP to a guy who publicly denounces you. Ryan is a loser globalist RINO. What earthly reason can you think of to put him a heartbeat from the presidency?
It’s a hypothetical. Trump and the GOPe are in negotiation. What if they [the GOPe] drew the line and said Ryan for VP or we will undermine you at every turn. I’m sure it’s on somebodies possible scenario list.
