Graham is one of those cases where I think a Tea Party challenge is worth the gamble. It would be one thing if he were representing a squishy-to-blue state ala Scott Brown. You aren’t going to elect better in Massachusetts than a guy like Brown. South Carolina isn’t Massachusetts, though, and I’m of the opinion the voters can elect whole a lot better than Lindsay Graham in their state.
The Tea Party won’t be spread thin with a presidential election in 2014. Will be able to focus like a laser on some of the worst RINO’s including Lindsey Graham.
