Surveys for 2016 and 2017 include measures of political attitudes, values, and affinities in 2011 as well as self-reports of turnout and vote choice in November 2012 and 2016.

More than 1700 variables measure attentiveness, issues, candidate assessment, vote intentions, presidential nominee preferences, media consumption, political information, religion, and demographics. Data in .csv, Stata, and SPSS. (Note: a 2012 survey was conducted but has not been released yet.)
