I'm kinda with Sammitch in supporting Kasich. I differ a little bit in that I think he is the GOP's best shot--short of the economy getting flushed down the crapper this summer--to carry the battleground states. Trump, imo, isn't going to see a ceiling until August (assuming he gets the nod). I just don't see a scenario--once again, short of the economy going into meltdown--that a Ted Cruz can carry states like Ohio, Virginia, Colorado, and Florida. While I understand these odds are still against him, I think Kasich could--on the other hand--put places like Michigan and Pennsylvania into play. If the GOP candidate can't put the Democrats on the defensive in these states then this is all a big waste of time and money.
All that said, I've got a few hours to decide whether to vote my conscience or attempt to be a spoiler vote in the primary with the other guys.
