Over the last two months there have been two major moves in the polls: Clinton’s meteoric rise coming from behind to being up by nearly 7% in the span of a week post DNC in late July and Trump’s consistent gains throughout August and September that peaked with Clinton’s pneumonia episode.
Since then there have been to micro-trends amidst volatile polls. Originally it appeared Clinton was gaining back her momentum, improving her 1.3% lead to 3.1% in the span of a week. That small trend reversed and Trump seems to be gaining ground over the last 5 days and is now only 1.3% back again. Trump was last this close on 7/28 which is when Clinton began gaining her post DNC jump. It will be interesting to see whether this first debate causes a jolt to get us out of this 1%-3% Clinton lead.

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)
16 Polls were released in the last three days with three of them impacting the forecast. Trump’s gains on Clinton have slowed down as there are fewer battleground states for him to grab.
Here are the polls that had an impact on the forecast:
IA Poll Trump +7 moves state from lean R to likely R
VA Poll Clinton +7 moves state from lean D to likely D
PA Poll Clinton +2 moves state from likely D to lean D
The above moved the forecast from the previous 286-252 to the current 284-254. The 30 point lead is Clinton’s smallest lead to date and inches Trump within striking distance on the eve of the first debate.
