Nate Cohn: “After a quarter-century of closely fought elections, it is easy to assume that wide leads are unsustainable in today’s deeply polarized country. Only Barack Obama in 2008 managed to win the national vote by more than 3.9 percentage points. The other big leads all proved short-lived.”
“But as Mr. Biden’s margin endures well into its second month, it becomes harder to assume that it is just another fleeting shift in the polls. Perhaps the lead is not just different in size and length, but also in kind. It’s possible the nation’s political stalemate has been broken, at least for now, by one issue: the president’s handling of the coronavirus pandemic.”
