This is a good moment to remember that there are real people made of flesh behind even the most public figures, and to wish Elizabeth Edwards a complete and speedy recovery.This doesn't mean Edwards is out for good, but that will depend more on Elizabeth Edwards than anything John Edwards can do.
Best wishes also go out to her husband. Serious illness is often tougher on the spouse than it is on the person who is actually sick. I know this for a fact. With two young children, John Edwards currently has all the burdens any man could shoulder.
Update: Well, no, he won't suspend campaign.
