I found evidence of Ralph Nader's influence in two recent news releases. The first news item is the lawsuit by Center for Science in the Public Interest against Coca-Cola over vitamin claims. The second news item is the opinion of Consumer Watchdog that refinery cutbacks have exceeded the drop in consumption.
Ralph Nader started Center for Science in the Public Interest in 1971 while he was still Director of Public Citizen.
Consumer Watchdog was founded by Harvey Rosenfield who was once a staff attorney for Ralph Nader's Public Citizen Congress Watch.
