@Lash,
Well, this certainly could be the case since there isn't a snowball's chance in Hell that she would give up her quest for power because of her health, but as long as the reporting of her alleged health problems remains on the fringe, it will have no impact whatsoever.
She'll need to fall to the floor or go completely incoherent at a MSM covered event for it to have any traction.
Hey, if she wins and her health removes her from the presidency, I'll be a lot more content with Tim Kain as president than her.
