George S. McGovern, the democrat U.S. senator from South Dakota known for his liberalism, died on Sunday at age 90. He also battled Nixon for the presidency in 1972.

U.S. Rep. Jim McGovern offered this statement on the passing:

“The world has lost a great and good man, and I have lost my inspiration, my mentor, my dearest friend. There is less hunger and poverty because of George McGovern.  There is more hope. He believed that one person can change the world, and he proved it every day. While Lisa and I will miss him terribly, we are comforted by the knowledge that he is in a better place. And we are celebrating a long and well-lived and uniquely American life.”
