It really is too early to tell, it depends entirely on how Trump is doing politically. It may look like he's doomed now, but there's always the possibility of something crazy happening like single payer healthcare passing that could change things dramatically. It's happened before. Reagan's approval rating was 35% in the beginning of 1983, and by the end of 1984 it was 53%, and he ended up winning 525 electoral votes and over 58% of the popular vote. And while there's nothing I can imagine that would get Trump numbers like that, I do think it's quite possible that he could be re-elected.
