Teabaggers normally out-perform their poll numbers, so I'm still hopeful either Broun and Gingrey can at least get to the runoff, though I'm not betting on it.
Georgia seems to like its "establishment" Republicans. Neither of their current senators are firebrands, and Sonny Perdue and Nathan Deal didn't come from the far-right. Neither Broun nor Gingrey will make it to the primary runoff, especially with Handel sucking oxygen from them with her Palin endorsement.
At this point, it appears that Perdue will definitely make it to the runoff, while it seems to be a race for second-place between Kingston and Handel. I don't see what would make many people vote for Kingston over Perdue, so I think Handel will probably eke out over Kingston to make it for the second slot in the runoff.
