The United States is a federal constitutional republic. It is the world’s oldest surviving federation. A constitutional republic is a state where the head of state and other officials are elected as representatives of the people, and must govern according to existing constitutional law that limits the government’s power over citizens. The government is regulated by a system of checks and balances defined by the U.S. Constitution, which serves as the country’s supreme legal document. In the American federalist system[12] , citizens are usually subject to three levels of government, federal, state, and local; the local government’s duties are commonly split between county and municipal governments. In almost all cases, executive and legislative officials are elected by a plurality vote of citizens by district. There is no proportional representation at the federal level, and it is very rare at lower levels. Federal and state judicial and cabinet officials are typically nominated by the executive branch and approved by the legislature, although some state judges and officials are elected by popular vote. The House of Representatives[13] has 435 members, each representing a congressional district for a two-year term. House seats are apportioned among the states by population every tenth year. Note
