Trump Continues to Slowly Close Gap on Clinton Cutting Her Early August Lead by Nearly 3 Points

Hillary Clinton’s lead topped at 6.8% on 8/6.  Donald Trump has been slowly inching forward ever since.  The lead is now down to 4%, the lowest it has been  since the wild swing post DNC where the polls swung nearly 5% in the span of 5 days.

The gap may be stabilizing around this 4% (straight average of last 10 polls combined is 4.1% with 6 of them 3%-5%).

Here is a trend of the 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)
