Zero point zero
Being serious I'd prefer them not to. I'd like to avoid a Constitutional crisis.
We'll be alright with Trump.
George W Bush being appointed by Kathryn Harris and the "conservative" branch of the Supreme Court could qualify.
The electors behaving as they're allowed to doesn't.
But, the butthurt would rise to proportions not seen since the Civil War, surely. Electors are too weak-kneed for that level of responsibility.
He didn't even win the popular vote so the whinge about the electors defying the will of the people is especially sketchy this time, too.
The founders specifically created the electoral college to prevent people like Trump from being elected by the unwashed masses. The irony is that "constitutionalist" conservatives should be the ones trumpeting about letting the electors make their decision. You know, like the late Antonin Scalia that Trump pretends to worship.
