Term limits just ensure the incumbent doesn't care about their last term. If they do a good job and the incoming candidates look lousy, they should be allowed to continue. Want to really make a difference? Get money out of politics. Big corporate donations and mega media are what drives the campaigns, including who gets on the ballot in the first place, not the voters.

I think term limits really depends. I get why it makes sense in the abstract and I would love to see it implemented but I've stopped really advocating for it as a long term fix. It just moves the "institutional knowledge" about how Congress works into the hands of lobbyists instead of Congress. The revolving door just gets worse. It would have to be something like term limits + campaign finance reform to make a meaningful impact. That's a noble goal but we've needed campaign finance reform for a while and no one seems to want to address it.

Age limits seems to be a good balance of making an individual Congress critter's term long enough to still have some sway/power/authority (instead of lobbyists) while making sure they don't blue screen on us during a press conference. Given such high profile issues with McConnell and Feinstein I'll be a little optimistic in hoping for some change.
