Checks and Balances
How do they help us
They help us by making sure that we the people have an equal say in what happens to the laws. It also helps that even though the president is the leader of the united states he cant controll us on his own because of the Checks and Balences. Congress has the power to pass laws but if the president vetos it or rejects it then it will not become a law, but congress can take it back change it and propose it again.
