In spite of V.O. Key, Jr.'s (1956) original insight that geography might be a relevant predictor of contested statewide primaries, this hypothesis has received little attention from political scientists. We test Key's hypothesis using data on gubernatorial and U.S. Senate elections to identify the effects of electoral geography on the structure of competition in primary elections. We contend that dispersed bases of electoral support greatly increase the costs associated with maintaining party cohesion. Our findings support the theory that a geographically dispersed electorate heightens the potential for intraparty factionalism. These results are robust across several measures of the dependent variable.23 pagesen-USAttribution-NonCommercial-NoDerivs 3.0 United StatesGeographic distributionPolitical party support -- United StatesKey, V.
