What politician has ever said that they would create term limits when they ran for office? There are a few. Many of the career politicians have made much more than they normally would have made if they had not been in politics. In addition they have to have a majority that agree with them.

Only way that this is going to occur is if there is a ballot iniatiative like the we have in certain states. These are not always made into law or changed by the legistlators. In 1992 FLorida voted for a bullet train(at government expense) and has anyone seen one in Florida.
