(Internet panel survey) The survey sample is constructed by first drawing a target population sample. This sample is based on the 2005-2007 American Community Study, November 2008 Current Population Survey Supplement, and the 2007 Pew Religious Life Survey. Thus, this target sample is representative of the general population on a broad range of characteristics including a variety of geographic (state, region, metropolitan statistical area), demographic (age, race, income, education, gender), and other measures (born-again status, employment, interest in news, party identification, ideology, turnout). Polimetrix invited a sample of their opt-in panel of 1.4 million survey respondents to participate in the study. Invitations were stratified based on race, gender, and battleground status, with an oversample of nine battleground and early primary states (Florida, Iowa, Minnesota, New Hampshire, New Mexico, Nevada, Ohio, Pennsylvania, and Wisconsin). Those who completed the survey (approximately 2.5 times the target sample) were then matched to the target sample based on the variables listed in parentheses above. Finally, weights were calculated to adjust the final sample to reflect the national public on these demographic and other characteristics (including correcting for the oversampling of battleground states). For more detailed information on this type of survey and sampling technique, see Vavreck and Rivers (2008). In concrete terms, the weighted CCAP sample we use in our analysis appears similar in levels of political interest to that found in the weighted 2008 ANES time-series survey.
