<b>Winner of the William Anderson Award of the American Political Science Association</b>Explores the role of state politics in shaping the national agenda during the 1980s. By focusing on the federal tax policy from 1978-1986, Berkman argues that a conservative political agenda slowly replaced the liberal agenda dominant since World War II. <br><br>The state roots model asserts that national policymakers, particularly members of Congress, are products of their state political systems and environments. Berkman applies this model to the tax-cutting policies that took hold nationally in 1978, before Regan came to office, and continued in the tax acts of 1981 and 1986.
