Beth Garrett has posted The Promise and Perils of Hybrid Democracy (The Henry Lecture, University of Oklahoma Law School, October 13, 2005) on SSRN. Here is the abstract:

Abstract:
For most Americans, democracy in the United States is not entirely representative in structure, and none of us lives in a pure direct democracy where laws are made only through popular votes. Instead, for over seventy percent of Americans, including those in Oklahoma, government is a hybrid democracy – a combination of direct democracy and representative institutions at the state and local levels, which in turn influences national politics. Hybrid democracy is here to stay, so we need to better understand how its components interact. But even if we were writing on a clean slate and had the ability to choose between a purely representative system and one with some elements of direct democracy, I think we would do well to adopt some sort of hybrid. A system that allows the possibility of the initiative and referendum provides a check on elected representatives beyond the accountability of periodic elections. In this Lecture, I will suggest some of the benefits that a hybrid system can provide in three realms. First, hybrid elections allow candidates to make more credible promises by running on a platform that includes simultaneous enactment of initiatives. The association of an initiative with a candidate may also provide a richer information environment for voters, although recent scholarship draws into question whether voting cues are invariably enhanced by the strategic use of direct democracy by politicians. Second, the initiative process provides a way to circumvent the self-interest of legislators in designing institutions of government. Third, the possibility of using initiatives to enact policy supplies political actors with a tool that can serve majoritarian interests and counter special interest influence in legislative bargaining. As Governor Arnold Schwarzenegger is demonstrating in California, governance by initiative profoundly changes the dynamics of interbranch bargaining, although it does not seem to be a sustainable strategy if used frequently. As I discuss these benefits, I will also underscore the dangers of hybrid democracy and discuss reforms that seek to reduce the perils while maximizing the promise of our hybrid system.
