the united states primarily uses which type of government
Elections in the United States The United States has a presidential system of government, which means that the executive and legislature are elected separately. Article One of the United States Constitution requires that any election for the U.S. President must occur on a single day throughout the country; elections for Congressional offices, however, can be held at different times. Congressional and presidential elections take place simultaneously every four years, and the intervening Congressional elections, which take place every two years, are called Midterm elections.
