Congressional campaign spending and the quality of democracy

Nearly all research on campaign finance overlooks important intermediaries between candidate spending and electoral outcomes. We consider the effects of campaign spending on a variety of factors important to the health of any democracy and political community: trust, efficacy, involvement, attention , knowledge, and affect. Our analysis of the 1994 and 1996 U.S. House elect ions shows that the effects of campaign spending lie more on the side of de mocratic boon than democratic bane. Campaign spending increases knowledge o f and affect toward the candidates, improves the public's ability to place candidates on ideology and issue scales, and encourages certainty about tho se placements. Rather than permit House members to mask their voting record s, incumbent spending helps improve the accuracy of citizen perceptions of the incumbent's ideology, Spending neither enhances nor erodes trust and ef ficacy in politics or attention and interest in campaigns. We conclude that campaign spending contributes to key aspects of democracy such as knowledg e and affect, while nor damaging public trust or involvement.
