The latest in a heated race: democratic Congressman Mark Schauer accusing his opponent of outsourcing jobs and Tim Walberg acting on the defense.
The Walberg camp called on the incumbent congressman to fix his TV ad on Thursday, claiming he took a quote out of context. But of all the money these candidates have spent on negative ads: are they helping their cause?
"I don't think it's good for American society," says voter Bob Pohl. "Because I think you're tearing someone down."
Most people we spoke to don't like them. But pollster Bernie Porn says regardless voters are listening.
"We'll always poll and they'll say 'no, no I'm not influenced by attack ads,' and you'll ask who they're voting for and they'll often site the issues or candidates based off of the ads," says Porn.
"It's a part of every election," says Richard Cole, MSU Advertising Department Director.
But Cole says both candidates should tread carefully.
"Any incumbent congressman, any former congressman has to be very very careful that every vote he gets with an attack, he isn't losing a vote," says Cole.
According to Cole, voters connect how candidates run campaigns to how they'll run their offices if elected.
But for a race as close as the 7th congressional district, pollsters say attack ads won't mean much in the end.
"It's going to depend on who comes out," says Porn.
