Frist is a GOPer. And if the Dems talk loud enough, the words "medical care", and "scandal" in the same sentences should doom him. Esp. if they can find a minority patient who died after being covered by HCA.
It's a simple formula.
I'll take it one step further. Expect someone to come forward to say that they were harmed from medical malpractice by Dr. Frist or some such nonsense. Count on it.
