Don’t know much about Derrick Grayson, but if he’s in the run-off against Broun, he’s my man. : )
I would rank Handel and Gingrey 1-2 on my list. Both are proven conservatives, and either one would be a historic selection: Handel would be the first Republican woman elected to either house of Congress representing GA, and Gingrey would become the first Catholic U.S. Senator from GA (too bad that Gingrey is so old).
Herman Cain should’ve run, even if just to serve for a single term.
