Someone else viewed as unbeatable has a hail-Mary opponent from the progressive left -- and we're not just talking about Gavin Newsom and Chris Daly! That's right -- the stridently anti-war soldier's mom Cindy Sheehan has declared her candidacy against San Francisco's House representative, Speaker of the House Nancy Pelosi.

Sheehan says she's running because Pelosi didn't move to impeach Bush by July 23. She's running as an independent and, along with the anti-war thing, is also running on a platform for universal health care.

No word if Sheehan's moved to San Francisco yet like she said she was going to (she currently lives outside Sacto) -- but hey, she could always rent Ed Jew's house. (Update: Ha! The Chron's conservative columnist Debra Saunders made this exact same joke! Liberals, moderates, conservatives, progressives: we all agree that Ed Jew is comedy gold.)

We found this picture on Nancy Pelosi's website. Just look at how unhappy both of them look to be with the other!
