tens of millions of Americans saw the candidates in action, directly, without a media filter. For many, the revelation wasn’t Mr. Trump’s performance, but Mrs. Clinton’s: The woman they saw bore little resemblance to the cold, joyless drone they’d been told to expect.

How much will it matter? My guess — but I could very well be completely wrong — is that it will matter a lot. Hard-core Trump supporters won’t be swayed. But voters who had been planning to stay home or, what amounts to the same thing, vote for a minor-party candidate rather than choose between the racist and the she-devil may now realize that they were misinformed. If so, it will be Mrs. Clinton’s bravura performance, under incredible pressure, that turned the tide.

[Previously, she had run] into a buzz saw of adversarial reporting from the mainstream media, which treated relatively minor missteps as major scandals, and invented additional scandals out of thin air.

Meanwhile, her opponent’s genuine scandals and various grotesqueries were downplayed or whitewashed; but as Jonathan Chait of New York magazine says, the normalization of Donald Trump was probably less important than the abnormalization of Hillary Clinton.

...

This media onslaught started with an Associated Press report on the Clinton Foundation, which roughly coincided with the beginning of Mrs. Clinton’s poll slide. The A.P. took on a valid question: Did foundation donors get inappropriate access and exert undue influence?

As it happened, it failed to find any evidence of wrongdoing — but nonetheless wrote the report as if it had. And this was the beginning of an extraordinary series of hostile news stories about how various aspects of Mrs. Clinton’s life “raise questions” or “cast shadows,” conveying an impression of terrible things without saying anything that could be refuted.

The culmination of this process came with the infamous Matt Lauer-moderated forum, which might be briefly summarized as “Emails, emails, emails; yes, Mr. Trump, whatever you say, Mr. Trump.”

I still don’t fully understand this hostility, which wasn’t ideological. Instead, it had the feel of the cool kids in high school jeering at the class nerd. Sexism was surely involved but may not have been central, since the same thing happened to Mr. Gore.
