She was out of sight for thirty days? Yep, rehab takes a while.
From observing a dozen-odd head injuries while serving in the Air Force.....there’s three basic levels. A ‘bump’ which results in you staying one night in the base hospital for observation. A ‘substantial concussion’, which results in you staying five to seven days. And a major brain injury episode, where you spend four weeks and someone usually discussing you getting a medical discharge with disability.
If she had walked out after five days, I don’t anyone would suggest anything. To have spent thirty days, there’s more to the health story and I think she’s got some permanent deal to handle.
Me personally? I think she’s trying to pick up some donor cash, and act as a person of influence on the 2016 race, rather than run herself. I suspect she’s got someone else in mind (not Maryland’s governor)...and trying to outcorner the Obama team’s choice of a personal pick from their players (likely Maryland’s governor).
