i believe each state can impose it’s own laws ( including term limits ) on it’s representitives. If the states will not pass the laws, the citizens can take up a petition drive and put the issue on the ballot, bypassing them completely. The individual reps and senators do not work for the us government. they work for the individual states ( that is how and why they are elected ). The citizens can redress the government with their greivences, and the petition and ballot drives are one way to redress the government...if i am wrong, please correct me so that I can think of another way to do it...
See post 23 - they tried it and failed.
