Frist could beat Hillary. But otherwise, I can think of few Democratic nominees where it would be a definite lean Frist. Biden, Bayh, Richardson, even Warner could beat Frist. He's like a less charismatic version of Bob Dole.
And he's a cat killer
What are you going on about?
I recently found out what people meant by calling hima cat killer.
When Frist was a medical student, he went around to cat shelters, adopted cats and said he'd give them a good home. He would actually perform experiments on the cats so he lied about giving the cats a good home.
Was it stupid for him to lie about this? Yes but I doubt it would stand in his way of becoming President. It certainly doesn't mean that he's unqualified for the office.
