Institutional and Individual Influences on the President's Veto

This article evaluates and compares "president" and "presidency" centered explanations of presidential activity with respect to one important presidential power, the veto. Using individual bill data for nine congresses characterized by divided party government, I estimate a logistic regression model of presidential vetoes. This contrasts with previous research, which has used annual aggregate data. Using individual bill data allows controls for objectionable legislation passed by Congress and enables me to measure and compare the "propensity to veto" of different presidents. I conclude that presidential vetoes are in substantial measure caused by Congress passing objectionable bills, but that even controlling for congressional behavior, presidents exhibit strikingly different veto behavior. Ford was most prone to using the veto, and Reagan, the least. Although external factors exert great influence on the president's veto decision, the individual choices and strategies of presidents also have an important influence.
