Research typically defines evangelical belonging as affiliation with an evangelical denomination, but this approach excludes many self-identified evangelicals, even though previous studies of religious groups find that self-identification is a powerful predictor of political preferences. Using data from the National Survey of Religion and Politics, we investigate the usefulness of self-identification for classifying evangelicals. The effects of three types of evangelical belonging (religious tradition-only, self-identification-only, and a combination of religious tradition and self-identification) on respondents' political attitudes, party identification, and vote choice suggest that religious tradition is a good predictor of political attitudes while self-identification is a good predictor of party identification. We conclude that self-identification and tradition are both important to understanding evangelicalism and politics in America.

To examine the effectiveness of mixed-mode methodology, this article draws on a study that used both online and paper surveys to collect data on a sample of the over 50 population in a small New England town. Respondents were offered the option of responding online or with a paper survey, an approach that addresses some of the major concerns about using online surveys among groups with limited Internet access while also reducing costs and simplifying data entry. The authors demonstrate that response mode does not have a significant effect on survey answers once demographic variables (such as employment and income) are added to the analysis. In addition, the results from this survey suggest that the Internet is useful as a tool to collect data from those over 50.
