This article provides an updated analysis of the institutional and organizational landscape surrounding the advocacy of and opposition to vouchers and other forms of school choice over the past decade at federal/national, state, and local levels. The politics of choice grew far more complex during the 1990s, with Republican control of Congress and the White House, the growth of the national charter school movement, congressional passage of pilot voucher programs, and the Supreme Court's 2002 Zelman v. Simmons-Harris ruling. Utilizing an Advocacy Coalition Framework, questions about the ideological motivations behind different forms of school choice, the particular programs that certain groups are likely to support or oppose, and the strategies--including the potential alliances and coalitions--that are increasingly employed around school choice policy are explored. A framework for understanding and analyzing policymaking in this area is offered, extending existing thinking on both school choice issues and education policy more generally.
