Why is Pence so high lol, there's no chance he wins if Trump is impeached and no chance he runs if Trump isn't.
I agree. But also:
If Trump is impeached, Pence would likely feel the need to perform his religious duty and pardon the former president. If Pence were to be nominated after that...we'd have the 1976 presidential all over again. Regardless of the nominee, 2020 should end badly for the Republican Party. Nobody likes a constant drama queen (The 24/7 Trump Reality Show) or his flunky who never had a chance to be in a similar position without riding the maga coattails into office.
