Well, Trump certainly is not only off the rails but lying upside down on the trackside.
During the campaign, I didn't like Kasich and I didn't even like Cruz that much, but they actually have emerged as people with principles, although Kasich is wavering and may endorse Trump.
I saw today that the Vice Chair of the GOP organization in DC has announced he's quitting and he'll vote for the Constitution Party (Libertarian) candidate. Nobody in their right mind can vote for either Trump or Hillary, and I simply wasn't going to vote. But now I'm rethinking my options and wondering if maybe voting 3rd party might be better. The Libertarians are very pro-abortion, but then so is Trump (who has gotten all of his wives from his stable of escorts -err, I mean, models).
I wish somebody would emerge as a credible third party candidate, because I bet that person would get a lot of votes from the rational members of both sides.
