I have no argument with your surmise that Hilliary’s poor health is keeping her so out of sight.
BUT
I think it is also because of her campaign handlers advice...
a. such miniscule attendance at her ‘rallies’ does not make for ‘good optics’
and
b. almost every time she speaks, her polls go down.
Result of a+b: keep her out of sight AMAP!
Exactly! You’re are right 100 percent. Nail on the head!
