What mechanism prevents one branch of the government from becoming too powerful?

The mechanism that prevents one branch of the government from becoming too powerful is the system of checks and balances. This system is built into the framework of the U.S. Constitution and ensures that the three branches of government—executive, legislative, and judicial—have separate powers and can monitor each other's actions. Each branch has specific powers that allow it to limit the powers of the others. For example, the executive branch can veto legislation passed by the legislative branch, while the judicial branch can rule laws unconstitutional, thereby keeping each branch in check and preventing the abuse of power.

The concept of checks and balances is foundational to the functioning of a democratic government, as it encourages cooperation and compromise among the branches, ensuring that no single branch can dominate the governing process or infringe upon the rights of citizens. This is vital for maintaining a balanced and fair political system where power is distributed and accountable.
