Will it be Senator or Mayor Schwarzenegger?

Governor Arnold Schwarzenegger was on the Tonight Show for a 7th time this week and left open his political future (after he wraps things up in Sacramento). Some believe he will run for the U.S. Senate next while others suggest a campaign for Mayor of Los Angeles is far more likely.

The conventional wisdom--if there is such a thing--is that he would prefer to be back in Los Angeles with executive powers and closer to his family than an even longer commute and being one of a hundred senators--albeit an incandescent one. Perhaps recent Schwarzenegger biographers Daniel Weintraub and Joe Mathews will shed some light. Below is his quote from the show:

I see myself as a public servant, not as a politician. I want to finish my term, and I'm absolutely convinced that if I do a good job, and a great job ... we always will get a job after that.
