I have zero problems and I do mean zero problems with injured or disabled lawmakers being replaced.Dem or rep,it is the rules and a strategery one needs be aware of in the event , well like now. He ,most likely,will live and not be replaced but never will cast another vote.
The problem is there's nothing in the rules about replacing an absent or incapacitated senator.
Everyone can get sick and be absent. That's not grounds for removal.
This is an extreme case, to be sure, but there's no mechanism for removal other than by a vote of the Senate, and that ain't gonna happen.
Reading between the lines, I agree.
OK, at what point do you make the decision? Do you replace him now? What if he recovers enough in 6 months that he could have resumed his duties? Do you say, "Sorry, we really thought you weren't going to make it. Our mistake."
