Back to Chris Christie.
His appeal is that he's bluntly fiscally conservative, while being sane on social issues and cognizant of an person on the other side of the aisle who is being reasonable in trying times.
While Christie's plaudits for Obama down the stretch might have been the last nails in Romney's coffin, I don't hold any grudges. Guy was in a tough patch and state/federal cooperation was crucial.
People are giving less and less of a shit about social issues, and just want a guy who's going to be a right bastard on spending. Christie is right up that alley and is a charismatic, emphatic, articulate, man for those times.
If I had to pick a spirit animal, I'd have to go with doggy.
