I agree with age limits but if the case is to reject a second term by Biden it will not happen. Truman was President when Presidential term limit was imposed but Truman was exempt because it changed while he was in office thereby grandfathering him under the old rule.

Actually the idea of a Citizen Congress is not truth. Often once elected the person seems to stay in office until well past retirement age in many instances. I remember my mom saying that when Chet Holifield went to Congress he debated on whether to become a Democrat or a Republican and choose Democrat because there were more Democrats in his precinct which gave him a better chance to win. My mom graduated from High School with Cam Holifield, Chet's wife, in 1919 and were life long friends so I know that to be a truth.

A Congress of Citizens would be one that was constantly in a state of radical change without any of them staying for more than two terms. Any other Congress would and is composed of people who have made their life employment that of politician. It would also be advisable to end employment of all civil service employees when a new President is elected. Since there is a vast number of civil service employees the hiring of those positions could be assigned to persons elected to Congress. Thereby assuring that no civil service employee will overstay his welcome either.

I am certain that the men who set up our government never thought of lifetime politicians. If you will recall many of the Founders were wealthy to begin with but many died in poverty after the war the establishment of our government.

As they always say the devil is in the details.

1) Would the age limits still apply if in the next 20, 40, 60 years life expectancies jump by 10, 20 or 30 years? And if life expectancies dropped by 10 years, then what?

2) Under the proposal someone 75 years old running for a first term could serve till they were 83, so to be fair could a 79 year old run if they were limited to one term?

3) Since a VP stepping into the presidency can serve for up to 10 years, would a 75 year old VP then be able to serve till they were 85, or would they be ineligible for reelection if they were over 79 years?

I do agree that congress would be adamantly opposed to limiting their own terms of office, Senator D. Feinstein being a good example, as was S. Thurmond.

The daily caller is definitely a right wing site, and it is rated iiffy too, by Media Bias, AllSides and Ad Fintes. Biasly tayes them as 83% accurate.
However, that doesn't mean they are always wrong. I think we need term limits both on house and senate candidates of 20 years or so. About age of say, 76 on how old one can be when one is sworn in is a really good idea. A lot has been said by Republicans about president Biden's sharpness, and not enough about Trump's, which is just as bad or worse, as he is bat shit crazy.
