Recent studies examining the role of money in state legislative campaigns focus on questions related to the amounts raised, the sources of the funds, and the effects of spending on election outcomes. Little attention, however, has been given to the possible impact of money on other aspects of the electoral process-namely candidacy decisions. Political practitioners often assert that money has an important influence when incumbents collect large campaign treasuries or āwar chestsā for the purpose of warding off potential challengers. While several studies address the validity of this proposition in the congressional setting, few have examined it closely in state legislative races. This study considers this possibility in an analysis of incumbent funding in primary and general elections in eight states. Findings indicate that incumbents often amass war chests and these sums negatively impact challenger emergence; however, this effect is partially mitigated by legislative professionalism. The dampening effect of campaign treasuries is found to be more potent in states having the least professional legislatures.
