Michael Goodwin of the New York Post has detected one clear lesson from this year’s presidential campaign.

Donald Trump may or may not fix his campaign, and Hillary Clinton may or may not become the first female president. But something else happening before our eyes is almost as important: the complete collapse of American journalism as we know it.

The frenzy to bury Trump is not limited to the Clinton campaign and the Obama White House. They are working hand-in-hand with what was considered the cream of the nation’s news organizations.

The shameful display of naked partisanship by the elite media is unlike anything seen in modern America.

The largest broadcast networks — CBS, NBC and ABC — and major newspapers like The New York Times and Washington Post have jettisoned all pretense of fair play. Their fierce determination to keep Trump out of the Oval Office has no precedent.

Indeed, no foreign enemy, no terror group, no native criminal gang, suffers the daily beating that Trump does. The mad mullahs of Iran, who call America the Great Satan and vow to wipe Israel off the map, are treated gently by comparison.

By torching its remaining credibility in service of Clinton, the mainstream media’s reputations will likely never recover, nor will the standards. No future producer, editor, reporter or anchor can be expected to meet a test of fairness when that standard has been trashed in such willful and blatant fashion. …

… The Times now is so out of the closet as a Clinton shill that it is giving itself permission to violate any semblance of evenhandedness in its news pages as well as its opinion pages.

A recent article by its media reporter, Jim Rutenberg, whom I know and like, began this way: “If you’re a working journalist and you believe that Donald J. Trump is a demagogue playing to the nation’s worst racist and nationalistic tendencies, that he cozies up to anti-American dictators and that he would be dangerous with control of the United States nuclear codes, how the heck are you supposed to cover him?”

Whoa, Nellie. The clear assumption is that many reporters see Trump that way, and it is note­worthy that no similar question is raised about Clinton, whose scandals are deserving only of “scrutiny.” Rutenberg approvingly cites a leftist journalist who calls one candidate “normal” and the other ­“abnormal.”

Clinton is hardly “normal” to the 68 percent of Americans who find her dishonest and untrustworthy, though apparently not a single one of those people writes for the Times. Statistically, that makes the Times “abnormal.”
