About the U.S.

Government and Politics

Power in the national government is dispersed, divided, and decentralized; it is also limited, directly and indirectly, by the Constitution. To protect certain individual rights and political liberties, this charter places explicit restrictions on the national government, principally through the Bill of Rights and the 14th Amendment. The 1st Amendment, for instance, mandates that "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances." The Constitution also establishes checks and balances among the three branches of government - the executive, judiciary, and legislature - each of which has its own independent institutional base and its own enumerated and implied powers. The branches, moreover, share responsibility for policy making at the national level. As a consequence of these characteristics, the Constitution issues an "invitation to struggle" over the direction of American public policy, while at the same time serving as the cornerstone upon which all of American freedom and success lies.
