Extensive Alex Halderman post at Medium begins:

You may have read at NYMag that I’ve been in discussions with the Clinton campaign about whether it might wish to seek recounts in critical states. Thatarticle, which includes somebody else’s description of my views, incorrectly describes the reasons manually checking ballots is an essential security safeguard (and includes some incorrect numbers, to boot). Let me set the record straight about what I and other leading election security experts have actually been saying to the campaign and everyone else who’s willing to listen….

Were this year’s deviations from pre-election polls the results of a cyberattack? Probably not. I believe the most likely explanation is that the polls were systematically wrong, rather than that the election was hacked. But I don’t believe that either one of these seemingly unlikely explanations is overwhelmingly more likely than the other. The only way to know whether a cyberattack changed the result is to closely examine the available physical evidence — paper ballots and voting equipment in critical states like Wisconsin, Michigan, and Pennsylvania. Unfortunately, nobody is ever going to examine that evidence unless candidates in those states act now, in the next several days, to petition for recounts.

This makes a lot more sense. As I wrote in my post last night, I have a lot of respect for Alex’s opinion .  And now we know the story in NY Mag had someone else’s fingerprints on it.
