well the Chamber spent 2.3 million in the runoff trying to defeat him, and he has already promised not to support McConnell for senate leader if the repubs take the senate... He also defeated a 22-year incumbent. count your blessings where you may.
The Chamber of Commerce couldn't buy Perdue off or defeat him. We don't know if he would've been a RINO or not. But he's more likely to be a real conservative after the treatment the establishment gave him.
I like that a Chamber of Commerce endorsement to the other guy might have caused his defeat.
