Eh, frankly, I’m not a big fan of age limits or term limits, I think they’re fundamentally undemocratic. If people in a state keep electing someone then it is their right to do so.
Banning people over a certain age or who have served a certain amount of terms doesn’t solve the core issue in such circumstances, that being gerrymandering, voter suppression, and wide spread misinformation and disinformation spread by bad actors. There are plenty of old representatives and senators who I have endless respect and trust for, and it would really be a shame if they were forced to leave office just because they hit some arbitrary number of years or terms.
