Ten Democrats Getting Chamber of Commerce's Help, and Happy to Have It

In Idaho, conservative Democratic Rep. Walt Minnick's campaign manager, John Foster, said the Chamber's ads "are about Walt's work in the district." The campaign has no plans to ask that they be taken off the air.

"Walt has always maintained his focus on the district first and put a lot less importance on what kind of political intrigue is happening in Washington, D.C.," Foster said in an interview. "We're a long way from the Hill."

And despite the volley of attacks from the White House, the Democratic National Committee and other party affiliates, Democratic leaders have yet to call on the Chamber to remove the ads.

White House spokesman Josh Earnest emphasized that President Obama's criticism of outside groups influencing the election, particularly the Chamber, was about transparency in the political system more than partisan politics, even though so much of the money is benefitting the GOP.

"The president believes it poses a threat to our democracy for a group like the Chamber to spend tens of millions of dollars, from undisclosed sources, in an effort to influence American elections," Earnest said, "regardless of the candidate they are supporting."
