Resumen de Sources of Competition in State Legislative Primary Elections
Primaries are an important but understudied component of American elections. In this article, I examine competition in state legislative primaries across 25 states during the 1994 and 1996 election cycles. My findings indicate that competition varies greatly and is affected by a number of factors on the state and district levels. The presence of an incumbent reduces competition, but strong district support for a party leads to greater competition in that party's primaries. Population size and social diversity do little to affect competition, but urbanism and unified party control have a positive impact. Further, legislative professionalism is associated with greater competition, particularly in open-seat races. Overall, the results have important implications for theories about the conditions that enhance or inhibit competition across different types of elections.
