Well for one I don't think Trump has any intention of doing 90% of the things he has stated he will do. Especially not something that he last mentioned in February according to Google and is not on his campaign platform on his website.
Secondly, the issue is a state one at this point. It would take 2 majority decisions to somehow erase that and even then, I wouldn't know where the decision would lie.
Thirdly, Trump is almost certainly going to lose at this point so that just piles on top of how many unlikely things it will take for this to happen.
