Jonah Goldberg describes at National Review Online the mainstream media’s complicity in Donald Trump’s rise to the top of the Republican Party’s presidential ticket.

By May, Trump had already received roughly $3 billion worth of free media, thanks to ratings-hungry TV networks. CBS chief Les Moonves summarized it well at an investor conference in February: Trump’s rise “may not be good for America, but it’s damn good for CBS.”

Many in the media were so willing to put clicks and ratings before country because the conventional wisdom was that Trump would fade or implode eventually. Why not gawk at the spectacle? And if Trump did get the nomination, many journalists calculated, all the better. What fun it will be to watch Hillary Clinton destroy Trump and Trump destroy the GOP.

Only slowly have the media come around to the realization that Trump is an actual threat, but now it may be too late because they have a serious “cry wolf” problem. Millions of Americans firmly believe that journalists are water carriers for the Democrats and will tune out much of what they have to say about Trump now that he’s the nominee.

You can start the timeline as far back as the World War II era. In 1944, Franklin Roosevelt told the country that if Republicans were returned to power, “even though we shall have conquered our enemies on the battlefields abroad, we shall have yielded to the spirit of fascism here at home.” The press nodded along.

In 1964, CBS News’s Daniel Schorr claimed that Barry Goldwater’s planned post-convention vacation in Europe was really an effort to coordinate with “right-wing Germans” in “Hitler’s one-time stomping ground.”

In recent years, as the distinctions between news and opinion, analysis and advocacy, reporting and click-baiting has blurred, the problem has only gotten worse.

Every election cycle, the GOP nominee is smeared as a racist by the Democrats or the press — or both. Representative John Lewis of Georgia trades in a bit more of his hard-earned moral authority each time he insinuates that the GOP nominee is like George Wallace or wants to bring back Jim Crow, and political columnists relinquish a bit more of their claim to objectivity each time they let his comments pass without condemnation or criticism.
