How did Rousseau's philosophy on liberty promote his political views of democracy?

Rousseau's philosophy on liberty promote his political view of democracy, so that there are more citizens who are magistrates than who are ordinary private citizens.

Explanation:

In Rousseau's democracy the people are both the subject and the sovereign and as such they both make the law and are subject to the law.

Although the people are both sovereign and subjects, the sovereignty of the people is based solely in the assembly, and thus when the people are no longer assembled they become subject to following the same laws that they have just created.
