Public Citizen is a watch group that attempts to protect the public from all kinds of anti-democratic efforts. One “stealth” group most don’t suspect is the US Chamber of Commerce. People know the Chamber represents business, but they may not realize that it funnels money into elections. The Chamber has purchased 3 million dollars worth of attack ads in California alone against candidates who would make business accountable to the people. The names of the specific companies giving money to specific campaigns, of course, will not be available to the public.
