I forgot about Rubio, who is the Establishment’s backup plan if Jeb doesn’t gain traction.
Rubio is not firmly in the establishment camp nor the base camp IMO. He’s got his amnesty problem of course - and others, but he’s far better than most estabs on most issues.
And let’s not forget this: if he hadn’t shown what is possible with his total defeat of Charlie Crist - unknowns like Mike Lee and Ted Cruz might not have even run two years later. I’m no Rubio guy, and he ticked me off with his Guiliani comments recently, but he’s not McCain or Graham or McConnell.
