The only good that can become of a Trump presidency is that it may destroy the Republican party.
I was telling myself that for a while; and then realized that it was just something I was telling myself to make me feel better. Trump couldn't destroy that party if that was his initial intent; they will happily swing their beliefs to whatever set brings them the most power. If he suddenly declared himself a Scietologist tomorrow, they would say that was the greatest philosophy they'd ever heard of. As it is I expect we'll see them distributing copies of "the art of the deal" at their next convention.
There were times that I wondered if Trump actually was setting out to covertly make the GOP look ridiculous, then I realized that is not something he is capable of in any manner.
