of course his opponent had some pretty and nasty negative ads, hopefully people are tired of that shit.
Thats exactly what happened here in Massachusetts
it was Kerry Healey (R) (White) vs. Deval Patrick (Black) (D)
She (Healey) put out attack ads stating that Deval supported "rape" due to helping out an inmate that was charged with rape (or something along those lines). She also put out other ads attacking Deval. On the flip side Deval Patrick probably put out only one ad that was directly aimed at Healey.
In the end, Deval wins due to Healey looking too "hard" and people not liking her ads. Apparently she tried to change up her image and it was (obviously) to late.
