So whats wrong with Grammy?.
She has been fine for 85 years (except for being racist) now she is suddenly ill with an undisclosed condition.
And close to death, she got released from the hospital and went home like a typical uninsured person.
OTOH, maybe 0bama arranged for home care so Grandma wouldn’t let slip anything “sensitive” to hospital personnel. He can certainly afford to set up hospital-quality care for her in her home. So she could be dying, but in a controlled environment.
