George Washington once said "The people must remain ever vigilant against tyrants masquerading as public servants."
Our forefathers saw political service as solemn duty and responsibility, but not as a career. Too often we have seen abuses of legislative power come from the long tenure of legislators in Congress and the relations they build with special interests. If we cannot have campaign finance reform then we must impose term limits to ensure that the civil liberties of the People come before preferential treatment to special interests with deep pockets no individual could ever hope to match.
Having new people in Congress every few years ensures complacency is dissolved and that more Americans have the opportunity to serve and offer their experiences to legislative process.
