Trump can actually get exactly 270 electors just by holding serve where he's supposed to and sweeping Pennsylvania, North Carolina, and Georgia. There is a very plausible scenario in which Trump hits 270 and gets the race called for him while all the other swing states are undeclared. Then all of them flipping blue under mysterious circumstances and bringing the total to 270-268 creates a scenario where just one faithless elector could cost Trump the presidency, assuming the Deep State cooks up some Russian interference bullshit as a fig leaf to get one guy to flip. If you're looking for a shitshow scenario to kickstart a civil war, something like that could well be it.
I just have a feeling it'll wind up mattering this year where it hasn't at any point before. It seems like the kind of obvious dumb loophole that always comes back to bite you in the worst possible moment.
