Abstract
Philip E. Converse has challenged the findings of a 1965 article, “The Changing Shape of the American Political Universe,” and other work by Burnham. Converse asserts that most of the very high voter participation which occurred before 1900 can be explained by a combination of electoral corruption, the absence of personal-registration requirements and other “undramatic” factors, and thus that the anomalies which Burnham reported are largely spurious. Issues of major importance for social-science explanation are joined. The present article attempts to demonstrate that intervening structural variables cannot come close to explaining all the post-1900 decline in voting participation and that the genuine existence of universal nineteenth-century rural corruption has yet to be demonstrated. These efforts to explain away anomaly are held to be unpersuasive. The weight of evidence supports the objective reality of the phenomena originally reported. This in turn means that more adequate conceptualizations are needed to integrate empirical findings than those which have hitherto dominated the voting-behavior research community.
