Even if Corker is as untrustworthy as you say, Tennessee Right to Life should certainly endorse him over Harold Ford, Jr.
As far as I'm concerned, I have no candidate in this race. Chattanooga Chafee, who is a slimy little creep with no core values and a bold-faced opportunist, bought this primary, and now that he has, he stopped advertising completely, while Junior keeps airing commercials. I may sound like a conspiracy theorist, but I wouldn't be surprised if Corker's entire candidacy was about running interference for Junior. It makes me ill.
And to those that think we have this race in the bag, think again. Even a lot of 'Rats I talked to in Tennessee believe that Corker was the weakest candidate we could put up against Junior, and the vibes I'm getting lately are proving that to be the case.
