Christie doesn't have "baggage", he's dragging around a bunch of live naval mines. For that reason alone, nominating him would be foolish.
Yes, yet still, believe it or not, one of the least foolish things the GOP could do this year. In my opinion (sorry Hillary!) the three (sorry 7!) GOPers with the strongest chances to win the general are:
1) Marco Rubio
2) Jeb Bush
3) Chris Christie
4) Rand Paul
5) John Kasich
6) Ben Carson (no chance what so ever, but I just had to add him cause he's black)
7) Carly Fiorina (no chance what so ever, but I just had to add her cause she's a woman)
Yes thinking about it, people like Ted Cruz might actually have an even higher chance of succeeding than Carson and Fiorina simply because even knowing some very tiny details about politics to begin with.
