The Roper Center has made available its entire collection of Primary exit polls. Primary exit polls datasets include standard demographic makeup of interviewee and questions pertinent to the issues of each state. Sample sizes for these studies usually range from 800-2,000 respondents. A “d” or an “r” next to a state signifies that the Democratic and Republican primary exit polls exist on separate datasets. Occasionally, only one or the other parties is polled.
Access to the NEP Exit Polls no longer requires an application.
