Updated Poll of Polls: Trump Closes Gap but Clinton Still Has Significant Lead

Donald Trump has closed the gap with Hillary Clinton when compared to two weeks ago.  Between 8/3 and 8/7 Clinton was ahead by roughly 6.8%.    For the last week, the gap has shrunk down to roughly 5.8% for 8/11-8/14.  This reverses a trend that began post the DNC where in the span of a week Trump went from a small lead to being behind Clinton by 7%.

Trump has been more on message recently.  It remains to be seen how adding Steve Bannon of Breitbart will impact his campaign.

Here is a trend of the poll of polls:

Of course the election is not about national polls and popular votes.  It’s about the electoral college.  Please see previous posts or click below for updated  state by state forecast of the electoral outcome.

Methodology:

  • Use national polls listed at Real Clear Politics
  • Weigh the outcomes by the sample size of each poll
  • Account for the different days spanned for the poll by allocating it out across the days.
  • Example a poll of 1000 voters taken across 7/2-7/5 would have a weighting of 250 voters for each of those days
  • For each day, take the previous weighted 7 days worth of poll data to compute a percentage for each candidate.  The rolling 7 days decreases the impact of large polls taken on a single day (large sample electronic polls)
