"A GOP source sends along this video, shot by a Republican tracker, of a union member supporting Democratic Senate candidate Elizabeth Warren outside of a debate Wednesday night in Springfield, Massachusetts. The cameraman asks the union member if he was at an earlier debate between Warren and her Republican opponent, Senator Scott Brown.
"Uh-huh," the union member says, nodding.
"Did you guys get fined if you weren't there?" the cameraman asks.
"Yeah," the union member replies.
"How much did you get fined?" the cameraman asks.
"A hundred and fifty," the man says, although he later adds, "It's two-fifty if you don't go.""
