The GOP has four five choices:
1. Nominate Rubio
2. Nominate Bush
3. Nominate Paul
4. Nominate Kasich
5. Lose
FTFY
I've got to tell you, I'm not so convinced John "God Wanted me to Expand Medicaid" Kasich could win a general election. I think his lack of diversity in his Ohio cabinet will be used against him in a major way in a general election. Additionally, if you think Jeb stumbled on Iraq, Kasich went from urging an invasion in 2002 to now saying he never would have gone in.
So Kasich can't win a general election because of lack of diversity in his Ohio cabinet and Jeb's links with his brother are not a problem?
Atlas is Bizarro World where Kasich can take a conversation about Trump and make into a conversation about Kasich. Meanwhile, back on Earth…
Republican voters care a lot less about the party's brand than Republican leaders do, and in general, don't care what their leaders care about. The alienation of the base from the leaders is part of the reason the GOP's favorability lags 30 points behind that of the Democrats.
