Schwarzenegger to run again; will he face the iPod candidate?

The Los Angeles Dog Trainer-Enquirer-Times announces that "Schwarzenegger All But Declares Reelection Bid" and that fine paper has no doubt already prepared itself to act once again as little more than a mouthpiece for the Democratic candidate.
...Speaking at a special election campaign event in this Central Valley town near Fresno, Schwarzenegger was asked by an audience member if Californians would get "a chance to vote for you again."

The governor then revealed what his campaign staff had been hinting for several days: "I'm going to make an official announcement on Friday, this Friday. I believe very strongly in follow-through. Follow-through is the most important thing. If you start something, you've got to finish it."
So, who - other than unknown political wonks - might he run against?
The San Francisco Chronicle said comedian Robin Williams and actor Warren Beatty are on the list of possibilities being discussed in Democratic circles.

The list also includes San Francisco Mayor Gavin Newsom, former White House chief of staff Leon Panetta and business executive Steve Jobs, the Chronicle said -- but none of those mentioned has said anything publicly about making the race.
We've already had Governor Moonbeam, how about Governor iPod? I don't know which of those fine choices would be best, they're all quite terrific.
