Peace activist Cindy Sheehan wants to snatch House Speaker Nancy Pelosi's congressional seat from her in November, but first she's going to need the help - and signatures - of 10,198 friends and supporters.

Sheehan was at San Francisco City Hall on Friday to take out papers for her independent run for Congress, but without those signatures from voters in the district, her name won't show up on the ballot.

"It's an uphill battle," said Sheehan, who vowed to run against Pelosi in July after the speaker refused to start impeachment proceedings against President George Bush. "But I'm excited about the signature-gathering process. It's going to be an opportunity to talk to people about our campaign."

The 50-year-old Sheehan, whose son, Casey, was killed while serving in Iraq in 2004, became the public face of the anti-war movement when she mounted a demonstration outside Bush's Texas ranch that lasted from 2005 to 2007.
