Christiecrats or Christie Democrats

[Stranger in a strange land]

None of them will. By the time 2016 rolls around, Christie will have the standard 5-8% of Democrats Republicans usually pull, maybe a little more. That's assuming he wins a primary.

Also, it's quite likely that, like McCain and Romney, he'll be forced to take a bunch of Hard Right positions to win the Republican nomination, which will turn off many of the Democrats he would have otherwise appealed to.
