One of the biggest barriers to a functioning democracy is inertia (name recognition), which is why we need term limits so badly. Ask any democrat, for example, and they'll tell you they want younger, more diverse candidates. But when asked to check a box in the spring of 2020 for president, the majority (plurality?) bypassed the female candidates, candidates of color, and the non-CIS candidate(s) to choose an old white man as their champion - and not even the liberal old white man at that. We need these old-ass MFers out of the way, for our own damned good.
Rather than term limits on elected office, I'd like to see term/time limits on how long a senator or representative can sit on the same committees. If legislators were being termed out of the powerful committees, I think the parties would not try so hard to keep people in office past their functioning years.
