It is issues exactly like this one which mean the Hildebeest has exactly zero chance as a Presidential candidate. I don't think she is going to run for this and a couple of other reasons.
Another one is that she does not give many speeches standing up. Mostly she uses a casual MO with comfortable easy chairs on stage with a moderator leading her in a discussion. She gave a speech the other day standing at a podium, and she had a death grip on both sides of it, almost as if she would fall over if she let go.
Another one is that pair of coke-bottle-bottom glasses she's taken to wearing. I think she has some kind of serious medical issue that affects her vision and equilibrium to the point where she cannot stand for any extended period of time.
