My favorite Democratic blogger, Salon's Mickey Kaus, is planning a run against Senator Barbara Boxer according to the L.A Weekly:

Pioneering political blogger Mickey Kaus took out papers filed to run for U.S. Senate in California, he told LA Weekly. The Venice resident said he'll run this year against Barbara Boxer for her seat. He said he took out papers at the Los Angeles County Registrar of Voters.

The Democrat has been centrist and even conservative on some of the issues on which Boxer has taken a more left-leaning stand, including immigration: He does not favor amnesty and favors a more restrictive national policy.

The journalist's Wiki entry says he's also "skeptical of affirmative action, labor unions (particularly automotive workers' unions and teachers' unions), and gerrymandering of congressional districts."
