A super PAC founded by former Democratic Congresswoman Gabrielle Giffords is calling out Senate Republican Leader Mitch McConnell for voting against gun control measures in a new radio advertisement.Americans Responsible for Solutions was formed by Giffords and her husband Mark Kelly, and is launching the spots in the Louisville and Lexington areas. Giffords, who was shot in the head during a 2011 shooting rampage in Tucson, Ariz., has been an outspoken proponent for gun control measures since retiring from Congress.The ad implores McConnell to listen to voters, and highlights 82 percent of Kentuckians favor background checks for gun purchases."McConnell opposed common sense checks to keep guns out of the hands of criminals," the narrator says. "Written by a Republican and a Democrat. Supported by law enforcement officers. It was a common sense plan that protected Second Amendment Rights. But Senator McConnell ignored the will of the people."Listen:The Senate rejected a bipartisan compromise on background checks last week, which McConnell voted against and led a GOP backed filibuster to defeat.In the aftermath of the victory, the McConnell campaign was celebratory in fundraising messages and social networking, but in a response to the Giffords ad it took a more reconciliatory tone."Sen. McConnell commends Gabby Giffords for her courage and perseverance, but in Kentucky we have a fundamental disagreement with a gun-control agenda," McConnell campaign manager Jesse Benton told USA Today. "President Obama's allies have been attacking Sen. McConnell on this issue for months but his support for Kentuckians' Second Amendment rights will not waiver."The Giffords group is also launching ads against Republican Sen. Kelly Ayotte of New Hampshire.
