Well, the reason the LA Times did its puff piece on McClintock, when it did so, IMO was to try to dilute the Arnold vote, which it most feared.
Had Tom been the front-runner, or running 2d with over 20%, do you really think the LA Times still would have covered him as favorably? That it would NOT have run extensive slam pieces on how his cuts would hurt "the children," "the environment," selling off parks, etc.? IMO, clearly it would have crucified Tom in that situation.
I'll betcha the LA Times endorsed Tom's last general election opponent, Daniel Gonzalez. Couldn't verify that online.
