Nigeria

Nigeria is a federal presidential republic modelled on the United States. The President is both head of state and government, directly elected, and shares power with a bicameral National Assembly and an independent judiciary. Its 36 states hold significant powers, and elections balance ethnic and regional interests across a large, diverse federation.

United States

The United States has a presidential system with a strict separation of powers between three co-equal branches. The President is uniquely both head of state and head of government, elected separately from the legislature via the Electoral College. Congress writes the laws and controls spending; the President executes them and can veto legislation; the Supreme Court interprets the constitution. This system of checks and balances means power is deliberately divided — the President cannot dissolve Congress, and Congress can impeach the President.
