"In the Wisconsin primary campaign—the critical first test—the senator from Massachusetts faced Minnesota Senator Hubert Humphrey, a hero of liberals going back to the 1948 Democratic National Convention speech in which he declared: "The time has arrived in America for the Democratic Party to get out of the shadow of states' rights and to walk forthrightly into the bright sunshine of human rights."
As his friend, ally and aide Harris Wofford recalled, "[Shriver] badly wanted Kennedy’s nomination to come through liberal support, not through an alliance with Southern conservatives.” While the young senator was being pulled to the right by many of his allies, “Shriver hoped Kennedy would find himself responding to a convention and a campaign in which the liberal wing gave him decisive support.”
To achieve this end, Shriver came to Madison as his brother-in-law Jack’s campaign’s coordinator in the critical 2nd Congressional district. Well aware that Humphrey was a favorite in the region—especially with the liberal community that clustered around the University of Wisconsin campus in Madison—Shriver set out to build Kennedy’s credibility as a liberal."
People like Shriver and Harris Wofford were the true promise of JFK's Camelot. They were trying to forge a new America during the second half of the 20th century. They blazed a parth and made a lot of gains and left a wonderful legacy, but America didn't continue to follow.
