From what I’ve read here on FR, DeMint and Rossi have ties. No ones perfect, though, and I certainly won’t fault Jim if he decides to endorse Rossi. Won’t affect my opinion of him.
I’m not ready to accept DeMint as the kingmaker yet. Splitting the GOP vote in an area where we just might have a good showing, is the type of “one step forward, two steps back” tack the GOP has consistently taken; they found a target or wanted to frame a debate, took careful aim, and proceeded to shoot themselves in the foot..
