Did you read the part in the wiki article about student unions? >>Every year between one quarter and one half of the membership turns over, and Gregory argues this creates a situation where elected student leaders become dependent on student union staff for institutional memory and guidance. Although Obama was president, Bill Clinton's former Chief of Staff, Leon Panetta, who is very close to him personally was Secretary of Defense and Director of the CIA while Bill Clinton's wife was Secretary of State. All top positions in the Department of Defense, CIA, and Department of State are connected to this very small group. It's amazing that Obama is president and Bill Clinton's closest allies are in top positions. Long after the Clintons are gone their influence will remain in the 'institutional memory'.
