The Commission on Presidential Debates (CPD) was established in 1987 to ensure that debates, as a permanent part of every general election, provide the best possible information to viewers and listeners. Its primary purpose is to sponsor and produce debates for the United States presidential and vice presidential candidates and to undertake research and educational activities relating to the debates. The organization, which is a nonprofit, nonpartisan corporation, sponsored all the presidential debates in 1988, 1992, 1996, 2000 and 2004.

Factcheck.org, a nonpartisan Web site that has analyzed the accuracy of major political speeches, debates, and ads since December 2003. Headed by an experienced journalist and funded by the Annenberg Public Policy Center of the University of Pennsylvania, Factcheck.org has been cited by members of all parts of the political spectrum.

Its core is its collection of presidential campaign television ads. Beginning with the first ads of their kind in 1952 and continuing through 2008, the site provides general election ads from the major party presidential candidates (and select third-party candidates). While the collection does not encompass every variation of every ad aired by these candidates, the site includes the historically significant ads from every election and is a good deal more comprehensive for recent elections.

The latest news, issues and polls on the Presidential election campaign.
