The Massachusetts Senate race has gotten quite heated, with Republican Gabriel Gomez calling Democratic Rep. Ed Markey "pond scum" for a web video that invokes Osama bin Laden.

"You know I've got four young kids, and they've got to sit there and they've got to see an ad with their dad, who's a SEAL, who served honorably," he told a reporter after speaking at the Newton-Needham Chamber of Commerce. "And for him to be as dirty and low, pond scum, to put me up there next to bin Laden, he's just got to be called what he is."
