Good start DeMint
Jim DeMint, Senator, South Carolina has introduced a term limit amendment to the US Constitution. It will take a lot of pushing from the States to make it pass.
I would suggest that term limits for Supreme Court Justices be added, too. They should serve a single 18 year term with a staggered appointment schedule so a new justice is selected every two years. This means that a two term president can’t stuff the court. The court also needs to be fixed at nine justices to keep Congress from playing games like they did during Nixon’s administration. In order to keep Nixon from appointing new justices, Congress reduced the court from nine justices to seven.
