Politicians of both parties are remembering former Democratic U.S. Senator Eugene McCarthy for his activism and public service. McCarthy died Saturday in Washington, D.C. He was 89. McCarthy served two terms in the U.S. Senate, and before that five terms in the House of Representatives. But his political zenith came in 1968, when he challenged President Lyndon Johnson for the Democratic party nomination. McCarthy didn't win, but his opposition to the Vietnam War turned into a crusade that led to Johnson's withdrawl from the race. Former South Dakota Senator George McGovern was a friend of McCarthy and another opponent of the war.
