Sen. Bill Frist, Tennessee Republican.
So named because when he was a med student, he lied to local no-kill animal shelters by "adopting" kittens, keeping them as pets for a few days, and then dissecting and killing the cats for his medical experiments.
First Senator Cat Killer tried to use the nuclear option to enable Bush to ram through extremist judges. Now he wants to run for president.

Americans ought to go all out to keep Cat Killer from becoming the next President.
