The Massachusetts race for Governor was between the Republican Kerry Healey and the Democrat Deval Patrick.
Healey is the Lt. Governor under Mitt Romney and she ran a negative campaign against Patrick. She lost the race and I think one of the major reasons was her campaign strategy. It was classless and offensive to many people even those who supported her.
The question stands, do negative campaigns work? I realize this is a generalized question and that every race is different but in general do they work?
