The Occurrence and Consequences of Electoral Mandates in Historical Context

Abstract

This study revisits the debate over electoral mandates by assessing the occurrence and consequences of landslide electoral victories since the 1860s. The study builds on Keeler's (1993) formulation of mandates in terms of the opportunities afforded by an election. Viewing elections as creating policy opportunities allows a more straightforward assessment of the relation between election outcomes and the legislative activity that follows. The idea of policy windows also avoids some of the criticisms directed at electoral mandates. Using public laws enacted from 1860 to 1998,1 find that landslide electoral victories precede less active Congresses almost as often as they precede surges of legislative activity. Using qualitative historical information, I further find that the legislative opportunities afforded by a landslide victory are conditional upon unity of the president's party.
