National elections and the autonomy of American state party systems

by James G. Gimpel

Traditional theories of party organization have emphasized two-party electoral competition as the force behind party unity in state politics. V. O. Key first advanced this theory in Southern Politics, where he concluded that party factionalism in the South was mainly attributable to the one-party character of the region. But this traditional theory does not fit all states equally well. In the states of the West, especially, parties are competitive, but political activity is centered on candidates, not parties. The theory of candidate-centered politics allows Gimpel to explain why party factionalism has persisted in many regions of the United States in spite of fierce two-party competition. Using interviews, polling data, elections returns, and demographic information, Gimpel contends that major upheavals in the two-party balance of presidential voting may leave lower offices untouched.
