Harold Ford, Jr's newest ad,"Big Issue," places Iraq at centerstage in this key Senate race. Opening with footage of GOP opponent Bob Corker declaring to "stay the course" juxtaposed over images of violence in Iraq, Ford uses the recently declassified National Intelligence Estimate -- it's first appearance in a campaign ad that we've seen -- to aggressively argue that "America should always be strong, but we've got to be smart and honest too. We need a new direction to win this fight." Check out the video here.
