John Edwards says he's considering another run for the White House, but he says he hasn't made a decision yet. The former U.S. Senator made the comment at a campaign-style stop at a former textile mill now used to help small businesses in Greensboro Friday. Edwards, who has said his vote for the war in Iraq was a mistake, again suggested the removal of 40,000 to 50,000 troops. He's also called for the rest of the troops to return home over the course of 12 to 18 months.
