Term limits would take a constitutional amendment.
Not going to happen for the simple reason that each congress creates its own rules, and they have a death grasp on this authority, short of a constitutional convention that takes it away from them.
i would add the rule that congresscritters (house and senate) will NOT be paid out of the federal taxes. they will be given a salary paid by the state they represent. if a state so chooses it can pay for housing for the group and that will be considered part of the salary. the individual states should have the ultimate authority over the people who represent those states.
No retirement is a huge first step.
I like pay for constitutionaly leagal work.
Termination for anything outside the bounds of our founding documents.
