Tom McClintock came within a fraction of a percent of winning the controller's race last year and he fits that box nicely.
You put up a Classic Conservative candidate and it's hardly a challenge to the dimwits. Why? Because it's easy to scare the minorities with labels-that-stick like Heartless, Rich, Pro-Big Business, Anti-Labor, Extremist Fundamentalist etc. etc. You want someone that can WIN, you've got to get a person who can make the opposition's causes his/her own - that's what GWB is so good at.
