Answer:
a constitutional system
Explanation:
The US is a democracy that is guaranteed and supported by the division of three constitutional powers, the lesbian, the judiciary and the executive. The executive branch is headed by the president, who takes direct action to enforce public policies. Legislative power is the power that creates laws, but also serves to review the president's attitudes. And the judiciary is the power responsible for enforcing the law. These three powers work harmoniously in a system of weights and balances, that is, one of their functions is to curb excesses of the other powers. Thus, the president's power is limited, preventing authoritarianism from occurring in the country.
