Christie v. Hillary. That's an interesting matchup.
I haven't paid much attention to Christie until now, but he sounds like he's trying to court moderates. That will probably make the primary season a living hell for him, because that's when the rightest of the GOP's right wing makes the most noise and screams the loudest for their candidates (Michele Bachmann, Rick Perry, Herman Cain).
Hillary probably learned from Bill, so she will sound as centrist as possible. He started out leaning pretty far to the left, but quickly moved to the center after his health care trial balloons were trashed.
Remember, he was instrumental in the repeal of the Glass-Steagall Act -- a major piece of DE-regulationt. Glass-Steagall was the depression-era law that prohibited commercial banks from engaging in the investment business. Some will disagree with me, but that repeal helped cause the financial s**t storm of 2008.
So if the next presidential election does turn out to be Christie v. Hillary, it will be fascinating to see which one can come across as the most extreme candidate (within their parties' parameters) while trying to gain as many "center" votes as possible.
