Much of what we know about turnout in American elections is based on national surveys of voters participating in presidential elections. Much less is known about voter participation in other types of elections. Using verified turnout and registration data, we surveyed registered voters to determine the demographic and attitudinal differences between two groups of voters: those who participated only in presidential elections and others who participated in midterm congressional, state, and local elections as well as presidential elections. We find that age, education, gender, social connectedness, personal contact with local public officials, and satisfaction with government services are significant factors in explaining electoral participation by registered voters.
