I still think Lamar Amexander might run, if his heart is in it.
Senator Sanctorum will run, if he wins re-election, but he's more likely a VP pick for someone to pick up there conservative credentials.
My sleeper is Senator Coryn from Texas, he's got a unique style and he scares the bejesus out of liberals and folks on lefty sights, they think he can kill'em. If they fear him, I like him.
Lets not count out any other governors who are being a bit quiet now, but will pop out of nowhere in 2007, if Sanford is one of those guys, he'll set the race on fire.
Romney and Owens have no chance anymore.
Another sleeper pick, the good ole governor from the state of Minnesota, and look out for a possible run from that states current junior senator.
I don't expect Sanford to get more than 65% of the vote in 06 in SC. Don't expect him to get less than 63%.
If he chooses, he could be a strong contender for 08.
