If it were only about the will of the majority, it would be the right of the majority to oppress the minority. The American Declaration of Independence and Constitution make it clear that this is not the case. There are certain rights which are human rights and which no government can displace. And when it comes to how you Americans exercise your rights under democracy, your hearts seem to be touched by something greater than yourselves. Your role in democracy does not end when you cast your vote in an election.
Democracy is essential to preserving freedom.
If no individual can be trusted with power indefinitely, it is even more true that no government can be. It has to be checked, and the best way of doing so is through the will of the majority, bearing in mind that this will can never be a substitute for individual human rights. Though many of us may yearn for one, I do not believe it will ever arrive. Tyrants are not moved by idealism. They are moved by naked ambition.
