The U.S. Constitution separates government powers into three branches: the executive, the legislative, and the judicial branches. The writers of the Constitution wanted to make sure that the government didn't get too powerful, so they made sure the power in government was balanced. Each branch of the government can check on the others to make sure they're following the rules and not getting too powerful. Throughout the United States' history, many people have challenged the balance of the government through impeachment trials, majority rule in the Legislative branch, and trials in the Supreme Court. Readers will be encouraged to think critically about whether or not the balance of power in U.S. government is truly balanced.
