Biden's Second-Term Mistake

The White House is whispering that next week President Biden will announce his intention to run for a second term, though the polls say that even most Democrats hope he doesn’t. The public understands what Mr. Biden apparently won’t admit: that electing an octogenarian in obvious decline for another four years could be an historic mistake.

No doubt it’s hard to walk away from the Oval Office after working for five decades to get there. Flying Marine One home for the weekends beats Amtrak. The chance to pull the levers of power is intoxicating, and that’s also true for the advisers who have pushed him in such a sharply progressive direction in his first term. They know Mr. Biden will lead wherever they want him to go.
