Can the president really do anything he wants?

No, the President cannot do anything he wants. The United States Constitution establishes a system of checks and balances to prevent any one branch of the government from becoming too powerful. The President is the head of the executive branch and has certain powers, but there are limits to those powers. The President must work with Congress to pass laws, and the Supreme Court can declare executive actions unconstitutional.

The President is subject to impeachment if he violates the law or abuses his power. In extreme cases, the President can be removed from office through this process. The President is also subject to public scrutiny and criticism, which can limit his ability to act outside of the law or public opinion.
