Lately I've started looking at Kasich as a reasonable alternative
Well, Kasich is a Democrat, and has admitted as such. So I guess if you're looking for an alternative between Establishment Hillary and Socialist Sanders, he's a good choice. But since he's vying for the wrong nomination, that just means you'll end up with Hillary or Sanders.
I'm still confused by the waffling of the Democratic voters. I can't figure out why any of them are supporting Hillary over Sanders, other than they think she has a better chance of winning. That strike me as being okay with Lucifer winning the election, because he's in the Correct Party.
