State election

The Roper Center is making available to researchers its entire collection of state election day exit polls. This collection consists of numerous studies dating back to 1978 right up to the most recent polls conducted in 2010. Questionnaires and computer-readable datafiles are available for each study. Typically, state election day exit polls consist of congressional and/or gubernatorial vote questions in addition to questions on important statewide and local issues at the time of the polls. Like national polls, state Election Day exit polls include basic demographic variables in each study. Sample sizes usually range from 800-2000 respondents.
