Cooke doesn't like Bush either: Jeb Bush: The Wrong Name at the Wrong Time: He’s not the candidate Republicans need for 2016. Not exactly a ringing endorsement.

I think most of them are Rubio guys, but really, deep down, they are losers. They want to lose gracefully so no one will say bad things about them.
