I think if they are cancelling the debate, then the news will be grim.
All of the acceptable family members seem to be descending on the hospital as we type.
Presumably Tory and Chow don't know though, so we still have no idea how grim the news will be. I can see them extending politeness to Doug who won't be able to make it, and because the media will be all about the presser and will completely ignore the debate anyway. Cancelling it doesn't have to mean the news will be grim.
