I’ve never really considered John McCain to be a friend of the press.

Silly me. I guess I was wrong about the Republican U.S. senator from Arizona. He is now telling the president of the United States to back off from his declared war against the media, which Donald Trump has labeled as the “enemy of the people.”

“That’s how dictators get started,” McCain said.

Well …

McCain denies calling Trump a would-be dictator, insisting he’s just spelling out what has happened throughout history. Dictators seek to weaken — if not destroy — the press, giving them an avenue to complete power.

McCain detests Trump, it seems quite clear. The senator’s loathing of the president, though, seems well-earned.

Candidate Trump once declared that he didn’t consider McCain — a decorated Navy pilot and one-time Vietnam War prisoner — a “war hero.” Trump said McCain was a hero only because “he was captured. I like people who aren’t captured, OK?”

Some of us thought that ridiculous assertion would doom Trump’s presidential candidacy. Hah! It didn’t happen. It seemed to energize his supporters.

McCain, though, has kept up his drumbeat of criticism of Trump. I happen to applaud the senator’s verve as he challenges Trump’s ignorance about Russia and now about the dangers of seeking to weaken the Fourth Estate.

Those of us toiled in the craft of reporting and commenting on events of the day don’t consider ourselves to be “enemies” of the people. I have never thought of myself to be anyone’s enemy, although I am certain some of individuals I’ve encountered along my lengthy journalism journey perceive me as their enemy.

As Sen. McCain has noted correctly, the president ought to tread carefully if he continues this fight with the media.
