MediaCurves.com reports a shift towards Obama among Democrats, Republicans and Independents who viewed Defenders of Wildlife's TV ad on Palin's wolf hunting policy. The Defenders of Wildlife Action Fund is still raising money to air the ad in key battleground states. The ad has been aired in Ohio, Florida, Northern Virginia and Michigan. They are hoping they can raise funds to play the ad in Colorado and keep it on air in all of these states between now and the upcoming vice presidential debate.
