Former Wisconsin Senator Russ Feingold, arguably one of the most progressive members the Senate has seen in decades, joined Current TV's liberal news host Keith Olbermann on Monday night to encourage more Democrats to support the "Occupy" protests sweeping the country.

"My sense is that there's great fear that this sweet deal that a lot of people have in Washington and New York, this unholy alliance between our government and our media, the financial markets and the financial businesses, that this unholy alliance is finally being threatened and challenged. It is a threat and an attack on every working American, and it's time that we upset the apple cart. I think they are nervous, and I know this has great potential."

He went on to say that one of the goals of the "Occupy" movement should be overturning the Supreme Court's "Citizens United" decision, which allows unlimited, anonymous corporate donations to groups seeking to influence the American electorate through the media.

"This is what's destroying our democracy..." he concluded. "Unlimited corporate contributions have to be stopped."
