Let’s consider for a moment Christie in the GOP debate. Can you imagine what he’d say about Perry’s backpedaling on Social Security? Could you imagine him letting Rep. Ron Paul (R-Tex.) get away with nonsense about America bringing 9/11 on itself? Ooof. I imagine he’d brush off Rep. Michele Bachmann (R-Minn.) with a shake of the head and a sly remark. (“Michele, that’s cuckoo land stuff. Mental retardation isn’t caused by a vaccination.”) And as for Romney, Christie would have a solid case to make that you really can govern as a full-throated conservative in a blue state.
