The worst that can happen if Arnold gets in is that they'll be in the same fix as now, minus the racist-sympathizer governor (Davis) and the IDs for illegals, which might make the difference between whether Al-Qaida hits us again or not. I could see this as a moral dilemma if Bustamente was a pro-lifer, but he's not, and a vote for McClintock is a vote for Bustamente. "Principle" that helps Bustamente win is no principle at all.
