She is losing the tussle between head and heart. The economy is better than it has ever been, but ordinary people don’t feel it

The defining question in US politics was asked 44 years ago this month. One week before the 1980 presidential election, Ronald Reagan and Jimmy Carter squared up to each other for a televised debate. A former Hollywood actor, Reagan was also proving a lethal Washington aphorist. At the close, he spoke into the camera: “Next Tuesday, all of you will go to the polls. You’ll stand there in the polling place and make a decision.” Watching at home were more than 80 million Americans. “When you make that decision … ask yourself: are you better off than you were four years ago?” Is it easier to buy things, he asked, is unemployment lower?

A few days later, voters gave their answer, handing Reagan a 44-state landslide. Every presidential contest since has been framed in large part by his simple, deadly question. Ask it in the final stretch of this election and you get to the great mystery of why the race remains so close.
