I think Jazzhead is on the right track. The conservative movement has to be aspirational, not mournful and paranoid. If you listen to a Trump speech, there is plenty of whining, but no workable solutions are offered. It's a downer. The person we pick to lead the party must be capable of speaking to a wide range of voters. You can go along way towards winning a man's vote by acknowledging his existence. Bush did that with hispanics and got 44% of their support. With Trump I'm not sure he knows about anybody other than blue collar factory workers rendered obsolete by NAFTA.
Yep.
And in Rubio, we had a candidate that:
1. had the home-state advantage in Florida (critical for any GOP win)
2. had a positive, aspirational message for *ALL* Americans
3. had a personal life story that embodied the American Dream (rags-to-riches, son of immigrants to President)
So naturally, the GOP primary voters hated him.
