Joe Biden didn’t make any major mistakes in his Friday interview with ABC’s George Stephanopoulos. That’s the best you can say. He helped himself only because, after a dreadful week, he didn’t hurt himself. No hits, no runs, no errors.

Stephanopoulos concentrated almost entirely on two topics: Biden’s health and his dreadful poll numbers, which threaten not only Democratic control of the White House but also their chance to control the House or Senate.
