I don’t think of 65 as “elderly.”
Liz Warren is younger than I am. More to the point, she is younger than Hillary.

I do. I think that the presidency is for younger more vital people, perhaps 45 to 60. Remember they will usually have 8 years. And someone like Grannie Warren? She has never had leadership responsibilities in her life. She is way over her head. No she is way too old, and there is nothing worse than old leftists.
It might be better if more of our Presidents were shown the door after 4 years.
Edmund Randolph, who introduced the "Virginia Plan" at the Constitutional Convention, wanted the executive branch to be headed by three men, drawn from different regions of the country, rather than one, fearing that a unitary executive would lead to monarchy. When he lost on that idea, he wanted the President to be ineligible for re-election. Something to be said for that.
