Practice 3 The United States is a federal union of 50 states. The District of Columbia is the seat of the national government. The Constitution outlines the structure of the national government and specifies its powers and activities. Other governmental activities are the responsibilities of the individual states, which have their own constitutions and laws. Within each state are counties, townships, cities and villages, each of which has its own elective government. All government in the United States is “of, by and for the people”. Members of Congress, the President, state officials, and those who govern counties and cities are elected by popular vote. Heads of federal departments are named by the President, and judges are either elected directly by the people or are appointed by elected officials. Voting ballots are unsigned and marked by the voters in private booths so that no one else can find out for whom a citizen is voting. Public officials may be removed from office for failing to perform their duties properly as well as for serious violations of law.
