“The Republican super PAC that has spent heavily to reelect Sen. Susan Collins (R-ME) is running a country song on Maine radio that mocks her opponent, Troy Jackson (D), for having children with his second cousin,” the Bangor Daily News reports.“The ad from the Senate Leadership Fund, which surfaced Tuesday, calls Jackson ‘weird,’ a ‘freak’ and a ‘creep’ because ‘he has two kids with his cousin.'”And the refrain: “If he’ll screw his own family, he’ll screw yours too.”
