What Drives the Voting on Abortion Policy? Investigating Partisanship and Religion in the State Legislative Arena

Abstract

Much of the public policy debate on abortion now centers in the nation's state capitals. This research assesses the impact of partisanship and religiosity on the voting behavior of state legislators. Recent research indicates that a legislator's religious affiliation and the religiosity of their home districts can be a powerful predictor of votes on abortion bills, but this research uses a unique data set developed to analyze voting in the Florida House of Representatives to re-test those ideas and test several new ones. This work challenges the notion that member religion or district religiosity is more influential than partisanship in predicting votes on abortion. Ordered probit techniques show partisanship, gender and legislator religion (for Catholic and Jewish members only), to be the most significant predictors of abortion voting behavior. A number of district characteristics are found to be less significant. Theoretically, this suggests that legislators fulfill their party obligations as trustee on the floor of the House, more so than following constituent interests in the classic delegate role, as originally noted by Burke.
