We have three branches of the government for order.. The Executive, Legislative, and Judicial branches. These were made so each one could keep the other two in check, and so we do not have a parliamentary government. . The legislative branch is made up of the two houses of Congress—the Senate and the House of Representatives. The most important duty of the legislative branch is to make laws. Laws are written, discussed and voted on in Congress. There are 100 senators in the Senate, two from each state. Senators are elected by their states and serve six-year terms. The Vice President of the U.S. is considered the head of the Senate, but does not vote in the Senate unless there is a tie. The Senate approves nominations made by the President to the Cabinet, the Supreme Court, federal courts and other posts. The Senate must ratify all treaties by a two-thirds vote. There are 435 representatives in the House of Representatives. The number of representatives each state gets is based on its population. For example, California has many more representatives than Rhode Island. When Census figures determine that the population of a state has changed significantly, the number of representatives in that state may shift proportionately. Representatives are elected by their states and serve two-year terms. The Speaker of the House, elected by the representatives, is considered the head of the House. Both parties in the Senate and the House of Representatives elect leaders. The leader of the party that controls the house is called the majority leader. The other party leader is called the minority leader. The power of the Executive Branch is vested in the President of the United States, who also acts as head of state and Commander-in-Chief of the armed forces. The President is responsible for implementing and enforcing the laws written by Congress and, to that end, appoints the heads of the federal agencies, including the Cabinet. The Vice President is also part of the Executive Branch, ready to assume the Presidency should the need arise. The Executive Branch is in charge of the administrative aspect of the government. It
