Complete List of Presidential Polls Used

Below we have a list of all the presidential polls used on this site. Only nonpartisan polls are used; polls taken by pollsters working for one of the parties are intentionally omitted. The date given is when the poll ended. The poll length is also given. The polls for each state are sorted in descending order of their midpoints. Incumbents are denoted by an asterisk.

The data are also available as plain text and in .csv format for use with Excel. In the latter, the first column is the day number of the midpoint (Jan. 1, 2008 = day 1.0) and the second is the poll length in days.
