From the ANES website (http://www.electionstudies.org/studypages/2004prepost/2004prepost.htm): The study, in part, maintains and extends the core of the NES time-series by collecting data on Americansí basic political beliefs, allegiances, and behaviors. It contains special instrumentation on Americanís views on foreign policy, the war on terrorism, and the Iraq War and its consequences. It extends the experiment on the measurement of voter turnout begun in 2002, and carries expanded instrumentation on inflation, immigration, gender politics, and gay and lesbian politics. It also includes the Comparative Studies of Electoral Systemís Module 2, which focuses on representation and accountability. The data also contain several religion variables, including questions about prayer frequency, importance of religion, attendance at religious services, and belief in the Bible.

Variables: 1,184
Weight Variable: WEIGHT1, WEIGHT2
Data Collection
Date Collected: Pre-election interviews averaging 70 minutes in length were conducted September 7 through November 1, 2004. No interviewing was conducted on Election Day, November 2. Post-election interviews averaging 65 minutes were administered November 3 through December 20.
Funded By
The National Science Foundation under grant SES-0118451, the University of Michigan Center for Political Studies, the University of Michigan Office of the Provost, the University of Michigan Political Science Department, and the University of Michigan Survey Research Center.
Collection Procedures
Survey data were taken utilizing face-to-face interviews.
Sampling Procedures
The design of the 2004 NES was marked by a return to the traditional time-series combination of area probability sample, face-to-face interviewing, and freshly-drawn cross-section. A notable design feature was the continuation of the experiment which was begun in 2002 on the measurement of voter turnout. Other design features included a question order experiment for evaluation of general direction of the country, additions to issue placements of importance follow-ups, and the administration of parallel sets of social group 'linked fate' questions to group member respondents who were female, black, or Hispanic. Pre-election interviews averaging 70 minutes in length were conducted September 7 through November 1, 2004. No interviewing was conducted on Election Day, November 2.

Post-election interviews averaging 65 minutes were administered November 3 through December 20. Randomization, employed for selection of half-samples to reduce overall interview length, and for question order within batteries, was implemented by the CAI instrumentation. The total sample included 1,833 eligible persons and produced 1,212 interviews. In the post-election survey, 1,066 persons granted re-interviews.
