Voteview allows users to view every congressional roll call vote in American history on a map of the United States and on a liberal-conservative ideological map including information about the ideological positions of voting Senators and Representatives. The original Voteview of DOS was developed by Keith T. Poole and Howard Rosenthal at Carnegie-Mellon University between 1989 and 1992. Poole and Rosenthal developed Voteview for Windows in 1993 at Princeton University and that work was continued by Boris Shor. The legacy version of the website is available at legacy.voteview.com. The new voteview.com combines the visualizations provided by the now obsolete Voteview desktop system, data and NOMINATE estimates provided by the old voteview.com web site, and up-to-date voting data from the current Congress with new search, download and visualization functionality.
