Methodology: For state polls, we calculate each candidate’s weighted polling average over approximately 45 days or prior eight polls. State polling is more limited than national, so we may pull from a longer sample period if a state has few polls. Polls are weighted using fivethirtyeight.com’s Pollster Rankings, which rank pollsters based on polling methodology and historical accuracy. We’ve chosen to exclude candidates who haven’t exceeded 3% over the most recent sample period.
