electors tend to vote the way their electorate does on principle, and also because they want to keep their job, even if there's not really any law requiring them to in most states
what you really have to worry about are those red states that have strong Annoying Orange support, because if he wins a majority in that state's general election, he'll get all of those electoral votes (except in two states but who cares about those!!!)
don't worry so much about the electors themselves being terrible and electing Annoying Orange, worry about the election system as a whole and how much it sucks because it will elect Annoying Orange
