It would have been helpful to see how long it took her to recover.
This video really doesn’t demonstrate anything. ACtually the fact the the editing repeats the episode so frequently after it happens suggests that it was really short.
Basically, looks like a “senior moment” which is not uncommon among people in their 60s from time to time.
(Not that I don’t think there is something seriously wrong with her, but this video doesn’t demonstrate it, IMHO.)
Ideally a President should be between 46 and 62. Younger than that, too inexperienced and older than that, well, look at Reagan near the end of his term. He fell asleep during cabinet meetings.
The problem is . . . it might get worse. Especially under the pressures of office.
