Enduring Rivals: Presidential Success and Support in the House of Representatives

Abstract

We compare presidents' legislative support and success at the vote level of analysis. In so doing, we remind readers that these two outcomes measures, collected by Congressional Quarterly, Inc., may or may not reflect presidential agenda preferences. Success refers to a victory for the president on his vote positions, while support refers to margin of legislators taking the same position on the vote as the president. The vote level provides numerous characteristics of the legislation itself that serve as useful predictors of these two presidential position outcomes. These include its substantive nature, the stage of the vote on the floor, and the issue area of the vote. In addition to the characteristics of the votes themselves, we also incorporate presidential resources and environmental conditions. Virtually all of the component variables within these three concepts contribute to explaining presidents' legislative success and support in the House. We also find that, while models of overall House success and support perform similarly, controlling for party coalitional support dramatically alters the observed relationships. Therefore, without this further analysis, scholars risk misinterpreting the relationship between the president and Congress. Although we have not measured influence, we believe that these findings raise important implications for scholars of presidential-congressional relations and also suggest avenues for further research.
