Identify four groups that help formulate policy. Briefly explain their roles in policy formulation

What will be an ideal response?

The public bureaucracy, think tanks and shadow cabinets, interest groups, and members of Congress. The public bureaucracy is the institution most often involved in policy formulation as they have a concentration of expertise. Think tanks are professional organizations that often contract to provide policy solutions to government clients. Interest groups not only often bring problem items the policy agenda but also provide potential solutions. Members of Congress are often interested in reforming problems and provide alternative solutions to the issue they place on the agenda.
