The HRC is looking like the scenario in the TV show the West Wing, where the president was looking for reelection but he might wind up as a jittering and physically and mentally afflicted person. So he and his staff hid his affliction from the public.
Is the presidency for HRC, ticking a box on a bucket list or ?
This is another reason why presidential candidates at least those that wind up on the final ballot need to get examined and investigated for fitness of mind and body.
Kaine is no Harry Truman, while HRC can be a 3rd term FDR.
