© 1977 American Political Science Association. This paper has benefited greatly from the assistance of John Land, my research assistant, and from the detailed critical comments of Morris Fiorina, Sam Kernell, Robert Erikson, John Kingdon, Ben Page, Gary Jacobson, Michael Cohen, J. Vincent Buck, Robert Bates, and Lance Davis. I could not take all their criticisms into account, but I am deeply grateful for their generous donations of time. Some of the data employed in this study were made available by the Inter-University Consortium for Political Research at the University of Michigan. I alone am responsible for the analysis and conclusions. Formerly SSWP 81.
