We also want to build understanding of the policy-making process itself and alert readers to the many opportunities they have to make their views known. Most readers may recognize that Congress has chief responsibility for making public policy. However, they may not be as alert to the critical role that administrative agencies play in implementing the laws that Congress enacts. Whether the Centers for Medicare and Medicaid Services in the Department of Health and Human Services or the Office for Civil Right in the U.S. Department of Education, such agencies have enormous influence over how programs are run and the services they deliver to citizens. Citizens may be particularly able to influence government decisions at the state and local levels where policymakers and administrators are easier to reach.
