"All the way to the convention"

All of this talk of Clinton running "all the way to the convention" seems somewhat silly to me. That path is still filled with about ten "ifs" and they all have to (unlikely) break Clinton's way.

What happens when she loses North Carolina?

Seriously, I think she's just trying to create a space for her supporters in Pennsylvania to not give up.

(And the insistence on Florida and Michigan may be as much about her next run as this one.)
