I had a good friend in elementary school who was epileptic, took phenobarbital to control it.
On CNN, Larry Sabato says that this is all a conspiracy theory, but Team Crooked should come out with her full medical history. That does not square with a stumble or a faint.
Wolf Blitzer wondering what Team Trump will react with. Sabato says Trump will be derogatory, so Tream Crooked should put it to rest, first. It will be put to rest if there is not another occurance, he says.
If I'm team Trump, I don't say anything. She stumbled, tell the voters to look at the video. That is not a health issue.
CNN says the video is viral. LOL.
Analysis - Anthony Zurcher, BBC News, Washington
George HW Bush once vomited on a Japanese prime minister. His son fainted in the White House after nearly choking on a pretzel. Franklin Roosevelt hid his serious health conditions, and John F Kennedy never spoke of his debilitating back condition.
The difference between these men and Hillary Clinton, however, is that her "overheating" episode comes in the home stretch of a presidential campaign where she seeks to tie Ronald Reagan as the oldest person ever elected to a first term as president.
Then there are the conspiracy theories about her health - some of them advanced by top Trump campaign surrogates - which will only become more prominent, particularly after Mrs Clinton left her press pool in the dark for more than two hours on Sunday.
Age has been a factor in several recent presidential elections. Both John McCain in 2008 and Bob Dole in 1996 would have easily shattered Reagan's record. Donald Trump, at age 70, has his own health questions to address.
Sunday's episode may end up being simply an annoying distraction for the Democrats. Now, however, people who would otherwise have shrugged off Mrs Clinton's health rumours will be watching her activity more closely.
