Mitt's goal in NH?

To win, and win big!

Mitt needs to totally destroy all the rest of the field in NH.
This will cause all the sources of money to all the other people left in the race to dry up.

This would also give Mitt a very good chance to go into SC and win there too.

A clean victory in both NH and SC would get Mitt to his real goal of having the nomination all wrapped up by Florida.

And lets not overlook this fact.
Mitt's goal is to have this all over by Florida so that from that point on he will not have to spend one dime running against any other Republicans.
After Florida Mitt wants this election to be "Mitt against Obama"
Not "Mitt against Rick and Ron"

So to make this as painless as he can, Mitt needs to win in NH next week, and win big.

Mitt needs to win big to be able to sweep into Sc and have that State not become a problem for him.

right now, Rick is just praying to get enough money to make a "last stand " in SC.
Rick known that his only real chance of overcoming Mitt's lead in this election is to beat Mitt in SC.

If Rick can win SC he can force this game into extras innings and perhaps all the way to the convention.

So this is why Mitt really needs to destroy the whole rest of the field in NH.
A big victory for Mitt in NH next week will be the signal that he is unstoppable, and that any money given to the other guy is a pointless.
