* The average includes the most recent poll from each source within the past ten days. If there are fewer than five qualifying polls, we look back, by date, until up to five qualifying polls are found. If five polls are found, and there are other qualifying polls on that same calendar date, those will also be included. No polls older than 30 days are considered in the average.
