The Trumpkins finagle to get the worst possible GOP candidate ever (and a horrible human being) as the nominee, and now they accuse conservatives who don't like it as being traitors. Great.
Two things: as bad as Hillary will be as president, we'll all still be here after four years. If we surrender to Trump and the Trumpkins, that will define the party for the next generation. Trump might be slightly better than Hillary, that's debatable. (KIng Barack couldn't wreck the U.S., and neither will Hillary. It's questionable that she'll be able to serve out even one term as she's turning into a doddering old wreck.)
But he also favors a number of very unconservative positions, and the thought of him at the control button on defense is more frightening than Hillary. Either way we're screwed.
