If Kerry wins New Hampshire, I'm not sure it will produce the boost that everyone thinks. After all, a lot of people will blame the compressed schedule, Kerry's "native son" status, and the Iowa bump for the win.
The following races could easily be evenly divided between Kerry and Dean.
Michigan seems to be the key to the whole Democratic race. It's the last big race before Super Tuesday.
If you recall, after McCain lost South Carolina, Michigan was his last hope for an upset.
Because Michigan is allowing internet voting, Dean should be the prohibitive favorite.
If Kerry wins Michigan, he's unstoppable.
If Dean wins, he won't exactly need miracle wins to grab the nomination.
