That's Mitt Romney,' says Davis, a former Alabama congressman who seconded Obama's nomination at the 2008 Democratic convention. The Davis ad highlights the national health care law derided as 'Obamacare,' which passed Congress without a single Republican vote. The 'Why I Changed My Vote Campaign' also features testimony from Jodi, a lifelong Democrat in Illinois, who says Obama has failed on her main issues of debt and divisiveness. The super PAC says more than 5,000 people have submitted stories of why they're changing their vote to Romney."
