The establishment types who think Jeb Bush can get the nomination and win the general election are in denial about reality. Did you not notice this thing called the Tea Party? They mostly rallied around Romney because he was the least unelectable of an unelectable lot. They realized that there was not enough time to have developed a strong bench, so they accepted it. They are not going to accept an unnecessary defeat the next time around. They just won't. They expect a conservative hero to show up and run. You run an establishment candidate, and people are going to have their expectations let down. And you know what happens when people's expectations are let down.
