When Democrats attack:

Massachusetts Republicans have released a video that they claim shows an aide for Democratic Senate candidate Elizabeth Warren physically assaulting an employee of the Massachusetts GOP -- but Warren's campaign says the man featured was a cab driver, not a member of Warren's staff.
