An important leader at this level is a mayor, who often works with a group called a city council. They make decisions about a city or town, such as how much to spend on libraries and parks.
One top state leader is the governor, who works with state lawmakers. They write ideas for new state laws, and the governor says yes or no. These decisions, like how long the school year is, affect people in a state.
The president is a top leader at this level, along with members of the U.S. Congress. They write ideas for laws and the president can sign them into law. One national law says that cars must have seat belts.
