This is a great video from OSPIRG that goes through their Ag Subsidies campaign, outlining the problem, solution, and what they are doing to stop Congress from subsidizing high fructose corn syrup and other ingredients in junk food. Part of their campaign includes going door-to-door across the state, and along with other state PIRGs across the country, to educate the public and build up support. In the first year they talked to over 800,000 Americans about this campaign.
