My point is this: No need to get personal when he is already down. Job performance is one thing. Personal attacks are another. Nobody is going to elect you as a Congressman in Ohio or Michigan because Obama plays too much golf, her butt is too fat, they take too many vacations or that he 'might' be a Muslim... etc.
Candidates need to stay on THEIR issue based message. They do not need to chime in on every topic of the day like Rush and Hannity do.
And yes.... NEGATIVE ADS are ok, but keep them related to job duties and job performance.
There is a difference between: "You policies allowed Willie Horton to get out of prison and kill again" vs. "You wife Kitty is an alcoholic plus I heard you had an affair with your staffer."
