The establishment GOP is getting desperate in their fear that the base is rejecting the presumptive heir, Romney. They’re floating the idea of Jeb Bush, just in case. Their delusion that the same people who reject Romney will embrace Jeb Bush is just more proof that they have never understood conservatives.
The understand Conservatives perfectly, they just don't like them very much. All those gun loving Bible thumping red necks just don't fit into their world very well. They want you to vote for them, but they don't want you to get uppity, and think that you can cross the tracks.
