I think she needs to see a doctor, a doctor of Psychiatry.
Also why does nobody ask to see her medical records if she could take power after Pence as the 3rd in charge. Or are her medical records not revealed for security reasons?
She clearly isn't playing with a full deck most every time she is wheeled out in front of cameras. Her slurred words, her inability to even know who the sitting president was. This is a senile old woman who isn't at even 80% functioning and clearly isn't even up to the job she has.
