Which principle ensures that no single political party can dominate the government?

The principle that ensures no single political party can dominate the government is checks and balances. This system is designed to maintain a balance of power among the different branches of government—typically the executive, legislative, and judicial branches. Each branch has specific powers and responsibilities, and they can limit or check each other's authority. For example, the legislative branch can make laws, but the executive branch can veto these laws, while the judicial branch can interpret them.

This framework not only prevents any single branch from becoming too powerful but also discourages any one political party that may control a branch from exerting unchecked influence over the entire government. By creating a balance, checks and balances promote collaboration and compromise, making it difficult for one party to monopolize power completely.

Other principles like federalism, democracy, and separation of powers play important roles in governance and the political system, but checks and balances specifically address the issue of preventing dominance by any single political entity.
