(02-09) 11:31 PST SAN FRANCISCO -- Anti-war activist Cindy Sheehan, who has criticized President Bush and other elected officials for their war support since her son was killed in Iraq, said today that she won't run for office against U.S. Sen. Dianne Feinstein. "I felt that putting pressure on her from the outside would be more effective than working from the inside," said Sheehan, 48, of Berkeley during a morning press conference.
