Updated Poll of Polls: Clinton Has Regained the Momentum after the Debate; Her Lead over Trump Largest in a Month

Donald Trump had a two months run where he cut down Hillary Clinton’s nearly 7% lead as low as 1.3% , followed by 10 days where the polls fluctuated between Clinton +2% and Clinton +3%.  Now it appears Clinton has regained momentum.  Clinton’s lead stood at 2.1% the day of the debate and has now improved for 6 straight days to 3.9%.  This is her biggest lead since 8/27.

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)
