2312 SEPARATION OF PARTIES, NOT POWERS Daryl J. Levinson* & Richard H. Pildes** American political institutions were founded upon the Madisonian assumption of vigorous, self-sustaining political competition between the legislative and executive branches. Congress and the President would check and balance each other; officeholders would defend the distinct interests of their different institutions; ambition would counteract ambition. That is not how American democracy turned out. Instead, political competition and cooperation along relatively stable lines of policy and ideological disagreement quickly came to be channeled not through the branches of government, but rather through an institution the Framers could imagine only dimly but nonetheless despised: political parties. Few aspects of the founding generation’s political theory are now more clearly anachronistic than their vision of legislative-executive separation of powers. Yet few of the Framers’ ideas continue to be taken as literally or sanctified as deeply by courts and constitutional scholars as the passages about interbranch relations in Madison’s Federalist 51. This Article reenvisions the law and theory of separation of powers by viewing it through the lens of party competition. In particular, it points out that during periods — like the present — of cohesive and polarized political parties, the degree and kind of competition between the legislative and executive branches will vary significantly and may all but disappear, depending on whether party control of the House, Senate, and Presidency is divided or unified. The practical distinction between party-divided and party-unified government thus rivals, and often dominates, the constitutional distinction between the branches in predicting and explaining interbranch political dynamics.

I. FROM BRANCHES TO PARTIES A. Madison and the Mechanisms of Political Competition According to the political theory of the Framers, “the great problem to be solved” was to design governance institutions that would afford “practical security” against the excessive concentration of political power.10 Constitutional provisions specifying limited domains of le￾gitimate authority were of minimal utility, for, as Madison explained, “a mere demarcation on parchment of the constitutional limits of the several departments is not a sufficient guard against those encroach- ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– 10 THE FEDERALIST NO. 48 (James Madison), supra note 1, at 308
