You only see her sitting. Can she even walk anymore?
Even on “her own” televised fluff interviews, Hillary is introduced while sitting, does not walk in stage, does not allow videos of her walking up stairs. In Sept Oct Nov 2016, she could only make 1 or 2 campaign visits a week.
I suspect that she cannot do more now. The only she did not run again, not run for VP to replace Biden in 2021.
