She had had multiple episodes while the cameras are rolling though this may be the worse, or if not the 2nd worse the 1st being when she had a brief seizure while talking to reporters earlier this summer. She then laughed it off blaming it on a very cold ice coffee she was drinking or something like that. This time they are saying it was the heat except it wasn’t overly hot and the humidity was low. I think her health was the reason why the format of that last “debate” with Matt Lauer as the host had the candidates sitting down. She has trouble standing up for long periods and is physically weak at this point. Folks voting for her may well be voting for a Kaine presidency. I shudder to think of someone with such poor health and lack of stamina being in charge during an international crisis.
