The impact of public financing on electoral competition: Evidence from Arizona and Maine

Does complete public financing of campaigns enhance electoral competition? Arizona and Maine implemented similar clean elections programs for state-level races in 2000, providing an opportunity to examine the consequences of public financing. Employing two measures of competitiveness, I find that clean elections programs in both states significantly increased competition in districts where challengers accepted public funding. These findings Suggest that public monies do not simply attract low-quality challengers and that access to campaign funds is an important determinant of competitiveness. As a result, while public financing programs are not panaceas for uncompetitive elections, such programs can enhance competition in races where money is accepted.
