Well, given that at least one county-level post had the same candidate for both parties, like it has for the past 10 years.... No negative ad there. 
I think the main deciding factor here in the Granite state is that the Republican Candidate, Scott Brown, was an ex-Senator from Massachusetts, and he REALLY misread the constituency's opinion on "attack the candidate via screaming about Obama" ads.
Oh, wait, I almost forgot the funding figleaf.
The "Political Action Campaigns" that were placing ads in support of "Anybody but an Obama crony. I don't care if they've voted against anything he's introduced. They're the blue side, they're a CRONY." Those guys went too far. The actual candidates are pure as the driven snow... {/sarcasm}
