The Roper Center for Public Opinion Research offers two tools for searching opinion poll datasets: iPOLL, which allows searching at the question level, and Roper/Express/, which allows searching at the dataset level. The Center archives national opinion polls back to 1935, both U.S. and some international polls. Holdings include survey results data from academic, commercial and media survey organizations such as Gallup, Harris Interactive, Pew Research Associates, ABC, CBS, Wall Street Journal and many more. Many datasets are available for instant download in ASCII or SPSS format.
For surveys with national adult or major subpopulation samples (such as registered voters, women, or African Americans), iPOLL can be used as the primary finding aid to locate datasets on particular topics or for specific time periods. For state, foreign, and other special samples, Roper/Express/ can be used to locate datasets by keyword (the abstract is searched), date, country, survey organization, survey sponsor, or type of sample.
