MADDOW: Tonight, a dash of truth. Seriously rich corporate interests are out to paint ACORN as a vast left-wing conspiracy against the American way of life. You can look at ACORN's primary political sin as they're trying to raise the minimum wage. ACORN has been caricatured by people, like Congressman King, as a corrupt, criminal enterprise that steals elections and turns a blind eye to prostitution. That's the story line the mainstream media has latched on to, as well. What you might not know from all of the breathless ACORN damnation coverage is what ACORN actually does. They do things like advocating for a higher minimum wage. They do things like helping low-income families file their taxes. They do things like helping low-income families find jobs. And as we discovered most recently in the healthcare debate, when industries sense a threat to their profits, they go into kill mode. They create corporate-funded purportedly grassroots organizations to derail and destroy whomever they believe to be the source of that threat. Say you're a company that doesn't really want the minimum wage to be raised. But you also don't want to be seen fighting ACORN yourself. What you do is you hire Richard Berman. And what you get is "RottenACORN.com," a grassroots-ish looking Web site dedicated to destroying ACORN. "RottenACORN.com" is run by something called the Employment Policies Institute, a nonprofit think-tank that happens to be run by Richard Berman, who also happens to be the man behind grassroots-ish Web sites like the anti-labor one, "UnionFacts.com." Also, "MercuryFacts.org." which assures people that there really isn't that much mercury in that fish.
