It appears that her coughing fits have really gotten worse.
What’s the back story on the barking?
She has to disappear every so often to recover from all the Drugs they pump her up with before major campaign happenings. I’m suspecting a lot of Prednisone (steroid) regimes follow by some off time.
Side note:
Have you noticed the imagery of Hillary has been changing. It started just before Super Tuesday. The media pictures all have her dressed in campaign form, mouth always agape a bit (it’s a women thing) and with her expressing some recognition of somebody in the distant horizon.
