In the United States, the separation of powers creates a system where political power is diffused rather than concentrated, providing multiple access points for interest groups to seek influence.1

Because the executive and legislative branches are distinct, interest groups must focus their lobbying strategies on both branches of government. Unlike parliamentary systems where power is often concentrated in the executive, the U.S. system grants significant authority to the legislature, making legislative lobbying a primary strategy. Furthermore, the judiciary plays a major role in policy making through its power to invalidate legislation, which makes litigation a vital strategy for many American interest groups.12

Additionally, the U.S. federal system divides power across multiple layers of government, often requiring interest groups to conduct simultaneous campaigns at both the national and state levels. This structure, designed by the founders to prevent government action, creates numerous "hurdles" that interest groups can navigate to either promote or defeat policy proposals.12
