My local and state reps are not as "out-of-control" as this nation's national senators and reps. Are you suggesting that each state could impose term limits on it's own national representation? Interesting thought. I don't know about the logistics or legalities of it. However, those constituents with the most influential representation, i.e. - MA, CA, NV, etc. would never go start the tide and the "also rans" would want more seniority representation. I don't think it would work at the state level if that is what you meant for national representation.
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...
