Russ Feingold is ballyhooing some rather strange sources:
In a release accompanying his first radio ad in Wisconsin, Feingold's campaign runs through a laundry list of conservative supporters. "The conservative group Americans for Prosperity, the 'nation's premier grassroots organization committed to advancing every individual's right to economic freedom and opportunity' and a major backer of the Tea Party movement, praises Feingold, saying 'I applaud Senator Feingold for voting against the 2009 Omnibus Spending bill and truly respect his principled stand against wasteful earmarks.'"
Also, FreedomWorks.
