I can't help but feel that the fact it was the top story of NBC's Nightly News and they were discussing political ramifications of his resignation or death (another networks too) something is really wrong.
I disagree. When something like this happens, the media has to speculate to keep interest.
jmfcst is right-- Somehow I dont think Johnson cares all that much right now if the media is speculating about this or that or not. When you have a brush with medical emergency, one surprising thing can be how casually the world goes about its business, as if nothing was happening. In Johnson's case, it's a little different-- he is simply reminded of how much his worth to the 'public' society as a human being is tied up through his position as a Senator.
I don't think my comment really was talking about how Johnson feels, I was going under if they had good news they'd tell us theory
