Why is constitutional supremacy important for maintaining democracy?

It is important because it establishes the constitution as the supreme law of the land. That means that every person, regardless of their social status, and every state, regardless of their wealth or size, have to obey the constitution. If the supreme court says that something is unconstitutional then it will never be able to exist, and if they say that something has to be done then it will have to be done because of the constitution.

Ithink it’s a : ) good luck on whatever
