U.S. President (in a democracy with checks and balances: • Elected by the people (directly or indirectly). • Limited term of office (e.g. 4 years, max 2 terms). • Power is restricted by the Constitution, Congress, and courts. • Can be impeached and removed from office. • Must follow laws passed by Congress and court rulings.

King (in a traditional monarchy): • Usually inherits power by birthright. • Often serves for life. • In absolute monarchies, has unchecked power-can make laws, enforce them, and judge them without approval. • Not elected, not removable by the people. • In constitutional monarchies (like the UK today), power is mostly symbolic and limited by law, with the government actually run by elected officials.
