When some senators retire, they decide to take lucrative lobbying jobs. Others go straight to Wall Street. But Wisconsin Democrat Russ Feingold, who lost his re-election bid in November, is continuing on his principled -- and often lonely -- path by starting an organization to combat corporate influence in politics, an effort he hopes will spark "a new progressive movement" that will truly hold elected officials accountable.

Launching on Wednesday, Progressives United is an attempt to to build a grassroots effort aimed at mitigating the effects of, and eventually overturning, the Supreme Court's infamous Citizens United decision that opened the floodgates to corporate spending in the U.S. electoral system. In addition to online mobilization, the political action committee (PAC) will support progressive candidates at the local, state and national levels, as well as holding the media and elected officials accountable on the group's key priorities.

"In my view -- and the view of many people -- it's one of the most lawless decisions in the history of our country," said Feingold of Citizens United in an interview with The Huffington Post. "The idea of allowing corporations to have unlimited influence on our democracy is very dangerous, obviously. That's exactly what it does ... Things were like this 100 years ago in the United States, with the huge corporate and business power of the oil companies and others. But this time it's like the Gilded Age on steroids."
