After serving as Minnesota attorney general, two terms in the U.S. Senate, a term as vice president and after serving as U.S. ambassador to Japan, Mondale was pressed into service again for the saddest of duties. Following the death of U.S. Sen. Paul Wellstone in a plane crash less than two weeks before Election Day in 2002, supporters turned to Mondale, then 74, as a replacement. U.S. Sen. Tina Smith, a friend of the family, managed the short-lived campaign. "He didn't hesitate," she recalled, though the duty was a brutal one. When he lost, Smith recalled, he was most concerned about the young people on the staff and volunteers who had already been through so much. "He didn't want them to lose hope, to lose faith in politics," she said. "That was his way. Always thinking of others."
Smith, too, found a trusted mentor in Mondale. When she was about to be appointed lieutenant governor, Mondale unearthed the original memo he had worked on with Carter about changing the vice president's role. "He wanted me to have it as a guide," she said. "He always made me laugh. He had this self-deprecating, no-B.S., dry Midwestern humor. He remembered things about people."
Larry Jacobs, director of the Center for the Study of Politics and Governance at the University of Minnesota's Hubert H. Humphrey School, as well as the Walter F. and Joan Mondale Chair for Political Studies, said the man he got to know was warm, funny, engaged and on top of political and policy developments to the last. After 17 years of teaching together, Jacobs says he still called him "Mr. Mondale."
In private as in public, he said, Mondale was "the most respectful, decent guy many said they ever worked with. He had strong views, but also felt like what you believe should not come at the cost of someone else's self respect."
Jacobs called Mondale "a builder of modern American government," launching budget reforms instrumental in creating the modern-day Congressional Budget Office — including the reconciliation process that President Joe Biden would later use to push the American Rescue Plan, with its massive coronavirus relief, through Congress.
Jacobs said Mondale also played a pivotal role in the career of a young senator who had lost his wife and daughter in a 1972 car crash that also injured his two sons. Mondale camped out in the hospital room with the recently elected Sen. Joe Biden, urging him to stay in the Senate, saying it could become part of his family, Jacobs recalled. Biden would later say that when he had to decide whether to run with Barack Obama, his first call was to Mondale, who persuaded him to join the ticket.
