The first TV ad of this year's low-key U.S. Senate campaign in Pennsylvania is now on screens in the state's biggest media market of Philadelphia.
Democratic U.S. Sen. Bob Casey on Wednesday began airing a TV ad touting the "Campus Save Act" that he authored and became law in 2013 to help prevent sexual assaults on college campuses and protect victims.
Republican U.S. Rep. Lou Barletta of northeastern Pennsylvania is trying to unseat Casey in the Nov. 6 election. But Casey has a big fundraising advantage and Barletta isn't getting any help from outside super PACs. Barletta's campaign says it expects to be on the air in Philadelphia soon.
On Sept. 21, former President Barack Obama is headlining a fundraiser for Casey and Senate Democrats in Philadelphia. Donald Trump Jr. is headlining a state Republican Party dinner that evening.
