As context, begin by looking into the nature of governments, and the major types of government. Consider why governments exist and how major political theorists have viewed the roles of government. Examine the founding of the United States and the creation of the Constitution through the lens of “collective action theory,” which helps explain why the US government is structured as it is.

Study the system of federalism, where sovereign power is divided between the national and state governments. Trace the history of federalism in the United States, as it checks government power, and allows for the resolution of political conflicts. Note how the balance shifted in the 20th century, from greater state authority to a much-expanded power of the federal government.

Probe the concept of civil liberties, as they delineate restrictions that government cannot impose. Learn about “selective incorporation,” the process through which civil liberty protections at the state level have been guaranteed through Supreme Court rulings. Then look at how the judicial system has interpreted and upheld freedom of religion, freedom of speech, and freedom of the press.
