would Christie as VP make Pennsylvania a toss-up?

[Landslide Lyndon]

And on a serious note, I think Romney's going to explicitly ignore anyone in office less than a full term, just to avoid the possibility of another Palin fiasco.

Romney needs some really boring white guy who no one will pay attention to. Christie's bully reputation and the fact that he probably hasn't been really vetted and no one from NJ can be assumed to be clean means he doesn't qualify.

And that's why he will probably pick Rob Portman.
