Watch out for unintended consequences with this. Term limits will just concentrate even more power in the hands of the two major parties, unelected bureaucrats, and lobbyists. Any independent voice either within a party (e.g., Ron/Rand Paul or Elizabeth Warren) or outside of the two parties (e.g., Bernie Sanders) would never get a chance to make a mark if term limits were in place. It would basically homogenize the two parties (further than they already are) since anybody that broke from the herd would be quickly replaced. The only constants year to year would be the bureaucrats and the lobbyists so they'd run the show and would be completely unaccountable to the voters.
