Cancer returns for Edwards' wife
I don't think, if I were in the situation Elizabeth Edwards is in, that I could share her positive outlook on her husband's decision to continue in his bid for the Democratic presidential nomination despite the return of her cancer. 
I think the idea of a grueling 20-month campaign might be more than I could handle, along with doing whatever it might take to treat the disease (her cancer has returned in a metastasized and incurable form).
"When this happens, you can go cower in a corner and hide, or you can be tough and go out and stand up for what you believe in," John Edwards said. "We have no intention of cowering in a corner."
