A Multivariate Explanation of Decreasing Turnout in Presidential Elections, 1960-1976

CPS National Election Studies from 1960 to 1976 are used to test numerous explanations for declining turnout in presidential elections. An electorate both younger and older, decreased political efficacy, decreased reliance on newspapers for campaign information, and less intense partisan identifications are the most important causes of decreased turnout outside the South after 1960. Increased political distrust and a hypothesized less politically interested electorate are not important factors. The same factors are present in the South, though other forces have led to increased turnout there.
