proclaimed to the public prior to anyone filing to run for Congress... or the White House. I'd go one step further, though... desiring to see if they have a malignant personality trait that would endanger either the office or the people if the individual won. (Like, the Dark Triad of trump's mental illness).
Since Reagan killed the mental health agencies and threw everyone out into the streets, we've had a couple of generations where hereditary mental illness, or at least having a passed-down predisposition towards a mental health condition, is making itself known. Obviously, those usually get worse as the person ages and is prone to some sort of dementia on top of the MH illness.
A plus to instituting this type of requirement is that it might actually work towards removing the last of the stigma that can still come when seeking treatment. Most importantly, tho, is we must never allow someone with a Dark Triad malignant personality type take the highest office of the land and run with it, unchecked. We're just asking to repeat this current decade if we don't do something to avoid it, IMO.
Making either of these two changes will probably require a Constitutional Convention, and we don't want to have one of those while the magas are in the majority or ascending toward it. If we tried it that way, we'd end up with a slimmed down version of the Articles of Confederation, and very little rights and privileges for anyone who isn't a white male in this country. BUT at the very first opportunity with a Democratic administration, I'd like to see a Convention called for publically, and all those things maga screams about right now, or trump demeans and strips of funding, should be noted and explained in plain 6th grade English language. No more wondering if "Shall" is a stronger action word than "Will", for example.
I would love to hope and dream of the day coming soon when we can put this evil of arrogance and cruelty behind us, and civility and community reigns once again.
