Good analysis on Grahamnesty, Mamzelle.
You’re right, having Palin personally intercede in the SC race could make the difference, as well as getting the Senate Conservatives Fund and Tea Party Patriots and other groups involved. You are right it would be an uphill battle, but I think it could be done.
You see, all the Dems and establishment SC GOP have to do to keep Graham in office is to make sure that the primary field is crowded and diluted. This is how Sanford, who is very unpopular, managed to retake #1 in a special election. And then the Democrats can vote in GOP primaries and make sure Graham gets in.
It's not as simple as just giving SC conservatives a hard time for keeping Graham in office.
If there is a state to start a third party--it is SC.
