One is TV:

2 others are on the radio. One is Gentleman George Voinovich, the guy who cleaned up after Kucinich and went on to become governor of and senator from Ohio (and I'm surprised never a VP) talking about 'Obama's highly partisan vision', on mostly blue collar classic rock radio, and one from the Black Men Vote superPAC, who mix a cut of Romney saying 'I'm not concerned about the very poor' while talking about how the GOPs policies don't fit their needs, on the local R&B station.
Very effective ads.
