I'm convinced of one thing. A Conservative Republican will not be running from the Senate, a Conservative will not be running from the House - that is pro-HR 4437. The only Governor that COULD win the nomination, is Tim Pawlenty (R-MN), but he has to win his governor's race first. I don't know if he is pro-HR 4437 or has caved to Bush's stance on illegal invasion.
I think Vicente Fox will soon be unemployed, he cold probably run pretty strong here.
