As I recall, when McGovern left politics he decided to be a “consultant” — a paid lobbyist troublemaker. He was astounded by all the bureaucratic hurdles he faced and palms he had to grease to go into a new “business”. Never mind that many of these rules he helped create, but he never thought they applied (or should apply) to someone like him. Moron.
McGovern was not a lobbyist, but he did purchase and operate a hotel that went bankrupt. He later said: "I ... wish that during the years I was in public office I had had this firsthand experience about the difficulties business people face every day. That knowledge would have made me a better U.S. senator and a more understanding presidential contender."
