The August and September polls were more accurate than the October and November one.
I am convinced this is true because I don’t think ANY of the pollsters, including Baris or Trafalgar, made an adjustment for those who already voted.
For ex, say you have a voter population of 500,000, but 200,000 vote early. You poll that and get one result. but in November you poll and it looks really good . . . because you have failed to account for the fact that you are polling a remnant of just over half-—but the ones voting the other way have already voted. It will be interesting to see if the pollsters come to this conclusion.
