Peace mom Cindy Sheehan said she plans to run against House Speaker Nancy Pelosi unless she introduces articles of impeachment against President Bush in the next two weeks.

Sheehan told The Associated Press Sunday that she will run against the San Francisco Democrat in 2008 as an independent if Pelosi does not seek to impeach Bush by July 23.

That's when Sheehan and her supporters are to arrive in Washington, DC, after a 13-day caravan and walking tour starting next week near Bush's Crawford ranch.

Sheehan announced in May that she was leaving the anti-war movement and selling her five-acre Crawford lot.

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.
