Answer:
1.
The power of the President is checked in the United States through the following means:
- Separation of powers: The U.S. Constitution divides power among three branches of government: the executive, legislative, and judicial branches. This division of power ensures that no one branch has unchecked authority.
- Checks and balances: Each branch of government has the ability to limit the power of the other branches through various checks and balances. For example, the President can veto laws passed by Congress, but Congress can override the veto with a two-thirds vote.
- Impeachment: The House of Representatives has the power to impeach the President for "high crimes and misdemeanors," and the Senate has the power to try and remove the President from office.
- Judicial review: The Supreme Court has the power to interpret the Constitution and determine whether actions taken by the President or other branches of government are constitutional.

To ensure that presidential power is not unlimited, the United States has several systems in place:
- The Constitution: The U.S. Constitution outlines the powers of the President and limits those powers through various checks and balances.
- Congressional oversight: Congress has the power to oversee the actions of the executive branch and can investigate the President and his administration. This oversight can help to prevent abuses of power.
- The courts: The judicial branch can review and declare actions by the President or other branches of government as unconstitutional. This can help to limit the President's power.
- The media: The media can act as a watchdog and expose abuses of power by the President or his administration. This can help to hold the President accountable and limit his power.
- Public opinion: The President is ultimately accountable to the American people, and public opinion can help to limit his power. If the President acts in a way that is widely unpopular, he may face political consequences.
