Can Schwarzenegger win a general election with only forty percent of the vote? Then he might want McClintock's support in the future. McClintock has made himself into a kingmaker, and if you're actually conservative, why are you offended by the thought that someone will be there to make sure Schwarzenegger stays to the right?
Arnold has already said he's serving only til the end of Davis's term. And Tom's behavior over the last few weeks has effectively ended his own career. I wouldn't vote for him for any office.
