In addition to Cohen, Davis and Sutherland, "Chief" creator Rod Lurie is listed as contributing $2,000 to both the Kerry and Clark campaigns in 2004. Co-writer Anya Epstein is listed as contributing $500 to the Kerry campaign.
Co-star Peter Coyote contributed $1000 to the Dem Congressional Campaign, $750 to Howard Dean, $500 to Socialist Bernie Sanders, $500 to Ralph Nader, etc., etc.
My point is, Hollywood can put out a movie that is close to the truth about the White House when they want to.
