Since it's going to happen, may as well have a thread to discuss it.

According to a report Tuesday in New York Magazine, a group of computer scientists and election lawyers have approached the Hillary Clinton campaign with evidence they believe suggests the election might have been hacked to make it appear that Donald Trump won the Electoral College when Clinton really did. The hacking claim appears to be based on concerns about tampering with electronic voting machines. We’ve looked into the claim — or at least, our best guess of what’s being claimed based on what has been reported — and statistically, it doesn’t check out.
There’s no clear evidence that the voting method used in a county — by machine or by paper — had an effect on the vote. Anyone making allegations of a possible massive electoral hack should provide proof, and we can’t find any. But it’s not even clear the group of computer scientists and election lawyers are making these claims.
...
We found no apparent correlation5 between voting method and outcome in six of the eight states, and a thin possible link between voting method and results in Wisconsin and Texas. However, the two states showed opposite results: The use of any machine voting in a county was associated with a 5.6-percentage-point reduction in Democratic two-party vote share in Wisconsin but a 2.7-point increase in Texas, both of which were statistically significant.6 Even if we focus only on Wisconsin, the effect disappears when we weight our results by population. More than 75 percent of Wisconsin’s population lives in the 23 most populous counties, which don’t appear to show any evidence for an effect driven by voting systems.7 To have effectively manipulated the statewide vote total, hackers probably would have needed to target some of these larger counties. When we included all counties but weighted the regression by the number of people living in each county, the statistical significance of the opposite effects in Wisconsin and Texas both evaporated.8
Even if the borderline significant result for Wisconsin didn’t vanish when weighting by population, it would be doubtful, for a few reasons. You’re more likely to find a significant result when you make multiple tests, as we did by looking at eight states with and without weighting by population.9Also, different places in Wisconsin and Texas use different kinds of voting machines; presumably if someone really did figure out how to hack certain machines, we’d see different results depending on which type of machines were used in a county, but we don’t. And Nate Cohn of The New York Times found that when he added another control variable to race and education — density of the population — the effect of paper ballots vanished.
