Turnout and Representation in Presidential Primary Elections

This paper provides a partial test of the widely-held assumption that preference primaries are the most representative element of the presidential nominating system. It notes that the average voting turnout in presidential primaries is only 39 per cent, compared with 69 per cent in the same states' ensuing general elections. The representative quality of these electorates is examined with data from sample surveys of the 1968 New Hampshire and Wisconsin primaries. A comparison of the primary participants with non-participants among each party's identifiers shows, first, that presidential primary electorates are demographically unrepresentative of their nonvoting fellow partisans in age, education, income, and social status. Second, primary participants have no more intense party identifications than do non-participants. Third, participants hold issue positions more strongly than nonparticipants do, and on some issues they even hold positions contrary to those of nonparticipants. Finally, both of the Democratic primaries overrepresented Johnson sentiment and underrepresented McCarthy and Kennedy sentiment. The author concludes that the preference primaries' claim to be the most representative element of the presidential nominating system may not be warranted, especially if and when the national conventions are reformed along lines such as those laid down by the McGovern-Fraser Commission. In any case, 1972 offers a unique opportunity to study the comparative representativeness of local, state, and national party conventions and the preference primaries.
