Complete List of House Polls Used
Below we have a list of all the House polls used on this site. Only nonpartisan polls are used; polls taken by pollsters working for one of the parties are intentionally omitted as they tend to be more "fun with numbers" exercises rather than attempts to gauge public opinion.
The date given below in column 2 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 asterisks.
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.
The site also has a page describing the House races, including brief descriptions of the situation, the names and photos of the candidates, and links to their campaign pages, Wikipedia entries, and state parties.
