There are some interesting elements to the following article in the Washington Post. More relevant are Thompson's thougths on 1972 presidential office candidates.
Being around Edmund Muskie "was something like being locked in a rolling box car with a vicious 200-pound water rat." Nixon "speaks for the werewolf in us." And Hubert Humphrey, the saint of long-ago liberalism: "There is no way to grasp what a shallow, contemptible and hopelessly dishonest old hack Hubert Humphrey is until you've followed him around for a while."
No doubt, these descriptions will suffice for the next round of political elections.
