Bush's voting base, were central in promoting the Teach the Controversy campaign. In some state battles, the ties of Teach the Controversy and intelligent design proponents to the Discovery Institute's political and social activities were made public, resulting in their efforts being temporarily thwarted. The Discovery Institute took the view that all publicity is good and no defeat is real. The Institute showed a willingness to back off, even to not advocate for the inclusion of ID, to ensure that all science teachers were required to portray evolution as a "theory in crisis." The institute's strategy is to move from standards battles, to curriculum writing, to textbook adoption, and back again, doing whatever it took to undermine the central position of evolution in biology. Critics of this strategy and the movement contended that the intelligent design controversy diverts much time, effort and tax money away from the actual education of children. Political battles involving the Discovery Institute 2000 Congressional briefing: In 2000, the leading ID proponents operating through the Discovery Institute held a congressional briefing in Washington, D.C., to promote ID to lawmakers.

The amendment was passed by the U.S. Senate, but was left out of the final version of the Act, and remains only in highly modified form in the conference report, where it does not carry the weight of law. The conference report language is commonly touted by the Discovery Institute as model language for bills and curricula. The Discovery Institute lobbies states, counties, and municipalities, and offers them legal analysis and Institute-developed curricula and text books they proclaim meet constitutional criteria established by the courts in previous creationism/evolution First Amendment cases. 2002-2006 Ohio Board of Education: The Discovery Institute proposed a model lesson plan that featured intelligent design prominently in its curricula. It was adopted in part in October 2002, with the Board's
