Republicans and Democrats began showing at least 30 new campaign advertisements in contested House and Senate districts across the country on Tuesday. Of those, three were positive.

At the national level, the two parties are battling over issues like national security and the war in Iraq. But Congressional races play out on local airwaves, and the flood of commercials amounts to a parallel campaign, one that is often about the characters of individual challengers and obscure votes cast by incumbents. Frequently lost in the back-and-forth are the protests of candidates who say the negative advertisements are full of deliberate distortions and exaggerations.
While Democrats have largely concentrated their efforts on the political records of Republicans, the Republicans have zeroed in more on candidates’ personal backgrounds.

Democrats are equally aggressive in their advertisements, going after Republicans on votes, ties to campaign contributors and, in the case of challengers, their own personal foibles. In one Democratic advertisement, the disgraced lobbyist Jack Abramoff is shown in shadows wearing a hat as an announcer notes that he made contributions to Representative J. D. Hayworth, Republican of Arizona.
