The labor-backed group Americans United For Change is continuing its public campaign against Congressional Republicans and in favor of the Democrats, with this new ad attacking them for saying "No" to progress during a time of crisis:"Just days into the new session of Congress, Democrats expanded health insurance for children -- the Republicans said 'No,'" the announcer says, repeating the same point about equal pay for women, the Obama budget and long-term prosperity.The ad will run on national cable for a week.
