"That prospect is so scary that billionaire donors -- and the political front groups they fund–are spending astronomical amounts to help reelect Feingold's hapless foe, US Senator Ron Johnson, R-Wisconsin. Arguably the most nondescript member of Senator majority leader Mitch McConnell's obstructionist caucus, Johnson was elected in 2010 on a Republican wave that is unlikely to hit again this year. It has been clear for months that the incumbent's only hope for winning reelection is a smear campaign against Feingold. The negative television ads and mailings that deliver the smears cost money. And here it comes. Johnson, a millionaire whose primary mission in the US Senate has been to serve as an errand boy for economic elites, is getting a last-minute boost from the oligarchy."
