In an effort to maximize the benefit of Colin Powell's recent endorsement, the Obama campaign is out with a new radio ad today touting the Republican former Secretary of State's support for the president, highlighting remarks he made in a recent interview with CBS News' Charlie Rose. The minute-long ad, which according to the campaign will air in Florida, Wisconsin, North Carolina, Virginia, New Hampshire, Ohio, Iowa, Nevada, and Colorado, replays a clip of Powell's October 25 endorsement, which he announced on "CBS This Morning."
