There are two things I noticed from frequent, albeit informal, examination of the polls and statistical models. First, there was a sudden and dramatic discontinuity in the slope of the statistics and predictions when James Comey announced his (suspiciously timed and still not explained) innuendo about Weiner's emails on Clinton's server, which he retracted. Second, as votes for Gary Johnson decreased, votes for Trump increased; the Libertarian votes seemed to become mostly Republican.
