This is what happens when both parties scrape the gunk off the bottom of the barrel, and then nominate it for president.
It forces people to choose who they hate less, instead of choosing who they support more. It put conservatives in the position of either abandoning their conservative beliefs, or supporting someone who is blatantly racist and sexist, and forced liberals to defend someone who was blatantly corrupt.
There is no way this wasn't going to get really ugly, really fast. (what's worse, both parties had to have seen this coming, and pushed ahead anyway, as if widening the political divide in the US was their goal all along)
