I understand what you are saying; but, I think her health is a big factor. I had often commented her at FR, during the 2016 campaign, that her lack of stamina/energy should be troubling to voters as the office of POTUS is a stressful position, requiring long hours. She simply was not physically fit enough for the office.
Also, after watching that idiot, John Kerry, the last couple of days, I think we have dodged 2 bullets when it comes to these two former presidential candidates.
Don’t even get me started on Kerry. He’s a POS with no talent, on his best day. Combine that with his narcissism and you have a volatile mix.
