†The average includes the most recent poll from each source within the past 30 days, up to a maximum of five. If five polls are found, and there are other qualifying polls on that same calendar date, those will also be included.

Including Third Parties

Calculated averages are not comparable to those for the Biden vs. Trump polls. As polling with third parties has been very limited, the polls included in the average are often different.
