WASHINGTON—House Speaker Nancy Pelosi is expected to win an easy re-election to Congress on Nov. 4, but not before her liberal San Francisco constituents get the chance to cast symbolic votes against the war she has failed to stop and the president she never tried to impeach.Voters will have the opportunity to try to replace the Democrat with one of her leading critics on both those issues.

Anti-war activist Cindy Sheehan, in her first campaign for public office, is running as an independent against Pelosi in California’s 8th Congressional District, which covers most of the city of San Francisco except its southwestern corner.

Like other critics on Pelosi’s left flank, Sheehan accuses the speaker of not using her power to cut off funding for the Iraq war and says she should have allowed impeachment hearings against President Bush and Vice President Dick Cheney, among other complaints.

“I think it’s very important to go up against the establishment and to challenge both sides of the problem, not just half the problem,” Sheehan said. “It’s time the people were represented, and not the corporate interests.”
