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 dates given are when the poll was conducted. The polls for each state are sorted in descending order of their midpoints. When the two leading candidates are within the margin of each other, their cells use a white background. When one is ahead, the cell is colored. Clicking on a state name takes you to a page with the polls shown graphically.
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, 2016 = day 1.0) and the second is the poll length in days. That is repeated after the pollster.
