I am inclined to take this as yet more evidence that Noah Smith is very wise in his opinion that people should say true things about the world outside the mediasphere, rather than greatly increase their error rate and erode their credibility by getting lost in the wilderness of mirrors of polls, perceptions, and possibilities. Why doesn’t Ezra Klein write more columns about how Joe Biden has, so far, been a very good president—and is perfectly capable of figuring out the point at which he has lost too many steps. And if he is going to write about politicians who have lost it, why wouldn’t concern-trolling Republicans about Mitch McConnell or Donald Trump be a better use of his time?
