Trump is not made out of anti-matter. Thus his presence on Earth has resulted in an incredible explosion that would not only destroy all life on Earth but possibly the entire planet.
I guess other than that, he's in effect forcing the Republican party to make a choice: evolve or die. They're refused to choose for years now, and its about time they did. And that's a good thing. This country needs at least two parties to maintain democracy as an institution.
Ohhh! I really like this take on it. He's a kind of political natural selection incarnated, very symbolic and edgy.
