Dems launch scathing new ad highlighting Romney's flip-flops

The Democratic National Committee (DNC) released another scathing ad attacking GOP presidential candidate Mitt Romney, targeting for a second time this fall the candidate's changing positions on political issues.

The newest ad comes in two versions, with a 30 second one airing in key swing states Virginia, New Mexico, North Carolina, Ohio, Pittsburgh and Wisconsin. The extended version lasts four minutes long and displays Romney's many alterations throughout the years.

The DNC earlier this fall created a website asking voters about , as well as releasing an ad showing how the former Massachusetts governor preferred that Detroit's auto industry "go bankrupt."
