Walter Mondale, Ex-Vice President and Champion of Liberal Politics, Dies at 93

One of his proudest legislative achievements, he said, was his leadership role in making it easier for the Senate to cut off a filibuster with 60 votes, under a rule change, rather than a two-thirds vote, as was previously required. One of his biggest regrets, he said, was his delay, until 1969, in turning against the Vietnam War.

By the 1970s Mr. Mondale’s name was on lists of possible candidates for national office. Dutifully, he wrote a campaign book, “The Accountability of Power: Toward a Responsible Presidency” (1975), in which he criticized the “imperial presidency” of Richard M. Nixon, and then joined the race for the 1976 presidential nomination.

The campaign went nowhere. “I remember that after a year I was running six points behind ‘Don’t Know,’” Mr. Mondale said in the 2010 interview. He ended the bid early, in 1974. In withdrawing, he said he lacked an “overwhelming desire to be president.” The comment would come to haunt him.

The Democratic victor, Mr. Carter, a conservative Southerner, was looking for a liberal running mate from the North who could help him pick up support in the industrial states. Mr. Mondale was at the top of everybody’s list, but he had mixed feelings until he got an agreement from the nominee that he would have a full-fledged policy role, expanded from the largely ceremonial functions assigned to most vice presidents.

Mr. Mondale’s chief of staff, Richard Moe, said Mr. Humphrey had been equally persuasive. “‘Fritz,’ he said, ‘if you have a chance to be vice president, you should take it,’” Mr. Moe recalled.

In office, Mr. Carter was true to his word in giving him major responsibilities in the White House, Mr. Mondale said in 2010. “Carter did listen to me a lot, I think,” he said. “I tried to avoid giving a win-loss record. But he was marvelous to me and to Joan. They never insulted our independence or integrity or position.”

Some in the president’s circle, like Zbigniew Brzezinski, the national security adviser, later belittled Mr. Mondale’s input as consisting largely of political advice. In one instance, Mr. Mondale argued unsuccessfully against imposing a grain embargo on the Soviet Union after its invasion of Afghanistan at the end of 1979.
