Although there are common threads across the nation in Democratic and Republican support, we find significant state-to-state variation in the nature of group influences on party identification. For many sociodemographic characteristics, group size conditions the importance of the characteristic for party identification, a finding consistent with a contextual theory of political behavior.

Although controversy and debate surround its measure-ment and stability, electoral scholars generally have acknowledged its importance since the publication of The American Voter (Campbell, Converse, Miller, & Stokes, 1960). Among the wealth of studies that assess party identification are investigations of its social group foun
