Abstract
This paper presents evidence that candidate issue positions have a measurable impact on elections for the U.S. House of Representatives. For eight election years, electoral margins of Northern incumbent congressional candidates were examined to test the proposition that “moderates” within each party are better vote getters than those whose roll call records reflect their party's ideological extreme. The effects of roll call positions on election results were estimated by examining the relationships between roll call “extremism” and vote margins with district presidential voting held constant as a control for normal constituency voting habits. Although no strong support was found for the proposition that Democratic Representatives lose electoral support when they take extremely liberal roll call positions, a clear pattern emerged for Republicans: the Republican Congressmen who are the best vote getters tend to be the relative moderates and liberals who avoid the extreme conservative end of the political spectrum. An analysis of survey data suggests that the small group of voters whose electoral decisions are influenced by their Republican Congressman's roll call performance are found within the ranks of a select group who are both free of strong partisan motivations and highly politically informed.
