There Really Was A Liberal Media Bubble
Groupthink produced a failure of the “wisdom of crowds” and an underestimate of Trump’s chances.

“Last summer, the United Kingdom voted to leave the European Union in what bettors, financial markets and the London-based media regarded as a colossal upset. Reporters and pundits were quick to blame the polls for the unexpected result. But the polls had been fine, more or less: In the closing days of the Brexit campaign, they’d shown an almost-even race, and Leave’s narrow victory (by a margin just under 4 percentage points) was about as consistent with them as it was with anything else. The failure was not so much with the polls but with the people who were analyzing them.
The U.S. presidential election, as I’ve argued, was something of a similar case. No, the polls didn’t show a toss-up, as they had in Brexit. But the reporting was much more certain of Clinton’s chances than it should have been based on the polls. Much of The New York Times’s coverage, for instance, implied that Clinton’s odds were close to 100 percent. In an article on Oct. 17 — more than three weeks before Election Day — they portrayed the race as being effectively over, the only question being whether Clinton should seek a landslide or instead assist down-ballot Democrats:
Hillary Clinton’s campaign is planning its most ambitious push yet into traditionally right-leaning states, a new offensive aimed at extending her growing advantage over Donald J. Trump while bolstering down-ballot candidates in what party leaders increasingly suggest could be a sweeping victory for Democrats at every level. […]
The maneuvering speaks to the unexpected tension facing Mrs. Clinton as she hurtles toward what aides increasingly believe will be a decisive victory — a pleasant problem, for certain, but one that has nonetheless scrambled the campaign’s strategy weeks before Election Day: Should Mrs. Clinton maximize her own margin, aiming to flip as many red states as possible to run up an electoral landslide, or prioritize the party’s congressional fortunes, redirecting funds and energy down the ballot?
This is not to say the election was a toss-up in mid-October, which was one of the high-water marks of the campaign for Clinton. But while a Trump win was unlikely, it should hardly have been unthinkable.1 And yet the Times, famous for its “to be sure” equivocations,2 wasn’t even contemplating the possibility of a Trump victory.3…..”
