Not sure McCain is coming back, quite frankly. Dr. Milton Wolf, the Kansas physician who ran for Senate against another Washington fossil (Pat Roberts), posted a couple of insightful tweets after McCain’s “announcement.” Dr. Wolf noted the blood clot discovered in the Senator cannot be detected by a routine physical, and the surgery required to remove it is quite invasive. The idea that McCain will be back in a week or so is wildly optimistic, at best.
On the other hand, it’s quite possible that McCain (and McConnell) knew about McNasty’s condition in advance and with the health care crap sandwich going nowhere, McCain’s required surgery became the rationale to postpone a vote.
Not likely he'll be allowed to fly for a while - could be a longer term recovery period.
I notice the media is not very inquisitive - he's to “friendly” with them. Anyone else they'd be all over this.
