Yet Another Amazing Coincidence

Drum notes that Trump’s approval ratings shot up 6 points after the director of the FBI decided to imply that his opponent was a crook less than two weeks before the election, generating a massive wave of negative media coverage at a time when an unusually high percentage of voters were making up their minds:
Some of this might be Republicans coming home. But compare Mitt Romney:
And when you combine this with everything else…the idea that the Comey letter did not change the outcome of the election ceteris paribus is massively implausible.
As a counterpoint, Andrew Sullivan — who is willing to discuss his hatred of Hillary Clinton with only the very greatest reluctance — remains confident that Hillary Clinton’s campaign tactics are the sole relevant variable. For example, she didn’t distribute her voters as efficiently in Electoral College terms as John Kerry and Al Gore chose to, and she did not contest Wisconsin (and, apparently, its 60 electoral votes) vigorously enough. Do these very compelling explanations mean we should ignore the effect that coverage of the Comey letter had on the race? I report, you decide!
