Id upvote TG a hundred times if it was possible for the truth that the black robes etc dont fear the public for them not enforcing the constitution.
Unfortunately with all the BLM, Antifa, tear down statue crowd doing the doxxing and picketing of black robes I fear that if the black robes do act out of fear they will not make rulings in favour of the constitution but in favour of the purple haired mob.
Capcomp and others: no to specified age limits, do you think justice Clarence is too old to make wise decisions? What about Sowell? is he too old to make a rational argument if he wasnt just a great historian but had chosen public office?
Also there may (or may not) be advances in geriatric healthcare that might make living past 120 possible with both a sound mind and healthy body. If that happens you will end up with the majority of voters being over 65 and they will hardly want someone their grandkids age telling what to do.
As for expanding the representatives to fewer constituents per representative the problem will be you will need a massive building to house 4 thousand or whatever number would be elected. Unwieldy, most will never get to make a maiden speech or get on committees or be able to do anything but vote according to their block. Better would be fewer representatives with less to do as the federal government would be tiny and concerned with little but defence and foreign affairs. Then at the state level have a member for every 20,000 or whatever and they do healthcare, education and all the things that currently DC does. Yeah, I know, it wont happen as DC will never give up power.
