Robert F. Kennedy said that, of all his colleagues in the US Senate, "The person who has the most feeling and does things in the most genuine way is George McGovern." One of the first Senators to oppose the Vietnam War and advocate US relations with China, McGovern is best known for his lopsided defeat by Richard Nixon in 1972. He died this weekend at the age of 90. Journalist and historian Rich Perlstein is author of several books including, Nixonland: the Rise of a President and the Fracturing of America. His obituary of McGovern appears in the current New Republic magazine.
