Here’s the latest speculation on the Veepstakes from Mike Allen and Jim Vandehei:
New Jersey Gov. Chris Christie, who is said by insiders to want it the most and also to annoy some aides with his aggressiveness; Sen. Marco Rubio, who is not being as seriously considered as popularly believed because aides don’t see him as experienced enough or appropriately vetted.
South Carolina Gov. Nikki Haley and New Mexico Gov. Susana Martinez are also seen as too untested and lacking the national experience that would assure officials at Romney headquarters in Boston that they weren’t walking into another Palin problem.
I like Christian Heinze’s summary of the speculation: Is Pawlenty more likely than Rubio?
