Walter Mondale, Mr. Carter’s vice president, told The New Yorker this week that anxious and angry voters in the late 1970s “just turned against us—same as with Obama.” As the polls turned against his administration, Mr. Mondale recalled that Mr. Carter “began to lose confidence in his ability to move the public.” Democrats on Capitol Hill are now saying this is happening to Mr. Obama.

Mr. Mondale says it’s time for the president “to get rid of those teleprompters and connect” with voters. Another of Mr. Obama’s clear errors has been to turn over the drafting of key legislation to the Democratic Congress: “That doesn’t work even when you own Congress,” he said. “You have to ride ’em.”
