Henry "Scoop" Jackson was a Democratic Party senator and, according to President Ronald Reagan, "a wise and revered statesman and one who probably understood the Soviets as well as any American in history." 
He sought the Democratic Party nomination for President in 1972 and 1976 but did poorly in the primaries. Jackson was known as a staunch liberal on economic and social issues, who was never the less strongly anti-communist in foreign affairs. He remained a popular U.S. Senator from his home state of Washington until his death in 1983.
