Aaron Russo died today of cancer. Russo sought (but did not win, after coming in first on the first two ballots) the 2004 Libertarian Party presidential nomination. He was writer and director of the controversial, conspiratorial movie America: From Freedom to Fascism, aiming at the income tax system and the Federal Reserve.
