A more thorough explanation:

Constitutional liberty is a fundamental right that is protected by the Constitution or Bill of Rights. It refers to the freedom that is guaranteed to individuals by the government.

For example, the freedom of speech is a constitutional liberty that is protected by the First Amendment of the Constitution. This means that individuals have the right to express their opinions and ideas without fear of censorship or punishment by the government.

Another example of constitutional liberty is the right to bear arms, which is protected by the Second Amendment. This means that individuals have the right to own and carry firearms for self-defense and other lawful purposes.

These examples illustrate how constitutional liberty is an essential aspect of American democracy. It ensures that individuals have the freedom to express themselves and protect themselves, while also limiting the power of the government to infringe upon these rights.
