I'd almost argue that it's not even great in the executive branch. It was an overcorrection from a wildly popular president that couldn't be unseated until he died in office and a wildly unpopular vice president took over.

To me, it's just inherently undemocratic to automatically disqualify a choice that might be the most popular one. I could see the logic a little better for a governor but for the U.S. Presidency, most people would not even want to keep going after 2 full terms. Maybe if you had the double-whammy of a world war and a great depression again, I could see someone not wanting to abandon ship in crisis, but that job would burn most people out.

If you look at the 2 term presidents after FDR, none of them even would've tried to go for a 3rd term if the option was there. It's a self correcting problem federally because that job has stress factors none of us can imagine.
