Poll averages are computed by weighting each poll based on FiveThirtyEight.com’s pollster ratings, then adjusting for the poll’s age, obsolescence, and for news and election cycle factors. After weighting, each poll is averaged together to generate The Capitolist’s Horserace Index weighted average. All calculations and weighting factors are public and can be viewed here.
