Based on this statistical analysis, Clinton may have been denied as many as 30,000 votes; she lost Wisconsin by 27,000. For the past two weeks, Clinton supporters (and Donald Trump opponents) have been grappling with the surprising results of this year's presidential election. I believe the most likely explanation is that the polls were systematically wrong, rather than that the election was hacked. It gave stressed-out Democrats something concrete at which they could point to say, this, this is why Clinton lost the election. Clinton lost the election because it was close enough in those Midwestern states for her to lose.
