Crawford, Texas ? Cindy Sheehan, the soldier’s mother who galvanized the anti-war movement, said Sunday that she plans to seek House Speaker Nancy Pelosi’s congressional seat unless she introduces articles of impeachment against President Bush in the next two weeks.

Sheehan said she will run against the San Francisco Democrat in 2008 as an independent if Pelosi does not seek by July 23 to impeach Bush. That’s when Sheehan and her supporters are to arrive in Washington, D.C., after a 13-day caravan and walking tour starting from the group’s war protest site near Bush’s Crawford ranch.

“Democrats and Americans feel betrayed by the Democratic leadership,” Sheehan said. “We hired them to bring an end to the war. I’m not too far from San Francisco, so it wouldn’t be too big of a move for me. I would give her a run for her money.”

Pelosi spokesman Brendan Daly said the congresswoman has said repeatedly that her focus is on ending the war in Iraq.

“She believes that the best way to support our troops in Iraq is to bring them home safely and soon,” Daly said in an e-mail to The Associated Press. “July will be a month of action in Congress to end the war, including a vote to redeploy our troops by next spring.”

The White House declined to comment on Sheehan’s plans.

She plans her official candidacy announcement Tuesday. Sunday wrapped up what is expected to be her final weekend at the 5-acre Crawford lot that she sold to California radio talk show host Bree Walker, who plans to keep it open to protesters.

“The land itself has historical value,” Walker said. “It is the first people’s movement of the 21st century, and it needs to be kept as the hallowed ground that it is.”

Sheehan announced in May that she was leaving the anti-war movement. She said that she felt her efforts had been in vain and that she had endured smear tactics and hatred from the left, as well as the right.

She first came to Crawford in August 2005 during a Bush vacation, demanding to talk to him about the war where her son Casey was killed in 2004. She became the face of the anti-war movement during her 26-day roadside vigil, which was joined by thousands. But it also drew counterprotests by Bush supporters, who said she was hurting troop morale.

Sheehan, who will turn 50 on Tuesday, said Bush should be impeached because she believes he misled the public about the reasons for going to war, violated the Geneva Conventions by torturing detainees and crossed the line by commuting the prison sentence of former vice presidential aide I. Lewis “Scooter” Libby.
