As much as I love my own concept of the world's first tricamerial legislature (at least at the national level), I'd say the odds of it happening are even less than the anti-17th amendment loons getting their wish to repeal the 17th. That is, it ain't happening.
Putting term limits on the tenure of federal judges is more feasible and desirable, if only we had the will power to do it.
One really off-the-wall idea that IS theoretically possible is getting the new Congress to elect Osacio-Cortez as the first freshman Congressman Speaker in history. Pretty much all you'd have to do is convince the entire GOP caucus to NOT put up Kevin McCarthy as Speaker (since they don't have the votes and they'd lose anyway so it would be a merely "symbolic" gesture to nominate him for Speaker) and instead vote with about two dozen or so rogue moonbat RATs (I'd be lobbying every member of the Democratic Socialists of America) in supporting Osacio-Cortez over Pelosi as Speaker because the latter is "not progressive enough".
On paper, that's pretty easy to do. But convincing Congressmen to actually do it is something else.
South Afrika was tricameral towards the end, mon. One chamber each for Whites, Coloreds (mixed race), and Indians (tons immigrated there, Gandi lived there for a while, that’s where he learned how to be a rabble rousing pseudo-marxist). The plan for Blacks was self-governing Bantustans.
As for judicial terms limits, I used to think that was a great idea but I don’t know, depends how long we control the White House/Senate. I bet a lot of rats would get behind the idea right now. If we get a couple more 45-55 year old conservatives on the Supreme it wouldn’t make a ton of sense for us in the medium term.
