Given that there seemed to be a lot of feeling in the GOP that Trump should step down a while back, can I hold out for faithless electors voting for Clinton, and Trump losing after all?
No. Trump won, and now possesses an incredible amount of momentum. But especially not for Clinton. If there was going to be a faithless elector plot, which there won’t be, it would be to parachute in someone like Mitt Romney and let the House choose him.
He’s probably going to have 306 electoral votes, so any plot would have to be pretty large. Even if someone was dumb enough to try, it would probably fizzle like the attempt by a few Republican delegates to get a “conscience vote” at the convention.
SCOTUS has unanimously ruled that states may punish or replace faithless electors: https://www.washingtonpost.com/politics/courts_law/supreme-court-electoral-college-faithless-electors/2020/07/06/cf88f706-bf8f-11ea-b178-bb7b05b94af1_story.html
