@HistoPol My understanding is if it is after the ballots go out they're sol and will need a write-in campaign. Until then I think it's up to the party. I am confident Trump won't be the nominee for the reasons you mention and more. But I'm not positive, obviously. But I think he folds (or is kicked out) before Super Tuesday. BUT, the Democrats can kick out candidates with Super Delegates (its why they have them) but the GOP cannot because they didn't craft that rule. At least as I understand it
