The Politics of Abortion in the House of Representatives in 1976

Abstract

The discussion in the U. S. Congress preceeding the passage of the 1976 Hyde Amendment, prohibiting the use of Medicaid funds for abortions, was described and the results of a multivariate analysis of the factors influencing the votes on the amendment in the House of Representatives were presented. Between June 24-August 10, 1976 there were 3 roll call votes on the amendment in the House of Representatives and during this period support for the amendment increased from 54%-69%. Multiple classification analysis was used to analyze the relative influence of 11 independent variables on the voting behavior of the representatives. The 11 variables included 1) the age, educational level, sex, and religious affliation of the representative; 2) the representative's party affliation, degree of constituent support, and previous voting record on liberal issues; and 3) the average income, racial composition, geographical location, and the % of urban residents in the representative's district. The factor which served as the best indicator of the representative's vote on the amendment was the representative's previous voting record on liberal issues. Those with more liberal voting records tended to vote against the amendment and those with more conservative voting records tended to vote for the amendment. The 2nd best predictor of amendment votes was the religious affliation of the representative. Catholic representatives, compared to Protestant and Jewish representatives, were more likely to support the amendment. Geographical location of the representative's district was a moderate indicator of the representative's vote on the amendment. Representatives from the south were more likely to support the amendment. The degree of constituent support for the representative in his own district was also a moderate indicator of the representatives vote on the amendment. The 11 factors together accounted for 1/3 of the votes.
