While people profess a disdain for politics, in a democracy politics is the primary vehicle for citizens to influence the decisions and decision makers that shape public policy at every level. This widely acclaimed work provides an overview of public policymaking in all its aspects along with basic information, tools, and examples that will equip citizens to participate more effectively in the policymaking process. It is intended for use in internships and service-learning programs, but will serve equally as a resource for any organized effort to involve citizens in community service and the exercise of civic responsibility. This updated edition includes an all-new case study on the issue of immigration, and all other case studies have been revised.
