The news in Columbia Journalism Review’s series, by Jeff Gerth, on the coverage of President Trump is not that the press went all in on a busted flush. That’s old news to readers of the Wall Street Journal, New York Post, and our own modest columns, among others. Until 2016, Mr. Gerth reports, “most Americans trusted the traditional media.” Today, though, America’s press “has the lowest credibility — 26 percent — among forty-six nations.”
