It is obvious that members of Congress are not going to enact term limits 'cause your not going to vote to fire yourself. What if Congress agreed to pass term limits effective 1/1/20. Effective 1/1/20, no one can hold any elected Federal office for more than 10 years combined. It wouldn't help us now but it would eventually get a form of term limits done. Once you have been in Washington for 10 years in any capacity your done. That would include ambassadorships or cabinet positions including Czars.
Just a thought regards
