In the mail: The Last Great Senate by Ira Shapiro.
The author spent 12 years working for Senators Gaylord Nelson, Abraham Ribicoff, Thomas Eagleton, Robert Byrd, and Jay Rockefeller and paints a “vivid portrait of the statesmen who helped steer America during the crisis years of the late 1970s, transcending partisanship and overcoming procedural roadblocks that have all but strangled the Senate since their departure.”
