Manufacturers target regulations and Sherrod Brown in Ohio

Brown is in a competitive Senate race against Ohio State Treasurer Josh Mandel (R). The Democratic senator has been the target of several political ads sponsored by conservative leaning outside groups this campaign season.

“The No. 1 concern right now for manufacturers is the unfavorable business climate due to regulations and taxes,” said NAM President and CEO Jay Timmons in a statement. “Manufacturers in America face a 20 percent cost disadvantage compared to our major trading partners. This must change if we are going to create jobs and compete.”

A NAM spokesman said the ad campaign is "a significant six-figure buy" that will run for several weeks in Ohio.

Brown's campaign took exception to the NAM ad.
