That's a total myth, if you're suggesting that California conservatives just don't vote if they don't have a real conservative in the race. That's no fact. Republicans had plenty of incentive to vote in 2002 - and Republicans did relatively well in overall numbers, due to Davis' relative lack of popularity... and Republicans won ZERO statewide elections. See Tom McClintock for an example.
Conservatives vote, if only because the perception is that Democrats are often too lazy to vote.
It still comes back to waking up and realizing the makeup of California voters. Doesn't it make anyone wonder for more than a second WHY Bustamonte has ANY tangible support, and WHY the only REAL candidate, McSpoiler, is hovering below 20%? I agree that Tom would be the best governor, but woulda, shoulda, coulda ain't gonna be worth a whole lot if Bustamonte creeps in.
