George S. McGovern, the three-term senator from South Dakota who carried the Democratic Party’s liberal banner in the Vietnam War era, launched a star-crossed bid for the presidency in 1972, and energized many of the leading Democrats of the past generation, died Sunday at a hospice in Sioux Falls, S.D. He was 90.

Family spokesman Steve Hildebrand confirmed the death to the Associated Press. The cause was not disclosed.
