Russ Feingold and John McCain largely made their names in the Senate fighting the power of special interest money.
But now as McCain fights for re-election in Arizona and Feingold tries to return to the Senate in Wisconsin, the authors of the McCain-Feingold campaign finance law are benefiting from the same sources of funding they once scorned.
Feingold defends his position saying the political fundraising landscape has changed dramatically since his first Senate run in 2002. But his opponent Republican incumbent Sen. Ron Johnson has branded him a hypocrite.
McCain is tapping super PAC funding to help his re-election bid. McCain has argued that he's simply taking advantage of the law as it stands after the Supreme Court's seminal Citizens United ruling.
