Yes, yes, Trump’s attacks on the media are over-the-top and wrongheaded. Yes, in some small way he’s undermining the credibility of legitimate journalism.

But here’s the headline the Boston Globe missed: The media had largely done that to themselves before he showed up. Believe it or not, the percentage of Americans who say they have a “great deal” of trust in newspapers is actually up since Trump took office.

Or rather it’s up from 8 percent to 12 percent. The percentage of Americans with a great deal or quite a lot of trust in newspapers hasn’t hit 30 percent since 2006, according to Gallup. The percent that have little or no trust in them whatsoever hasn’t been below 30 percent since 2008.

So what’s the point of the editorial-page protest? This avalanche of invective won’t move Trump supporters. The Globe, Times, Chronicle, etc. made it clear months ago that these readers weren’t valuable to them. And how much self-indulgent virtue signaling can the media do before it loses its charm?
