How much can a good finish help a candidate?

A near-win finish in Iowa gave Rick Santorum a million-dollar day in fundraising, followed by another million-dollar day.

The Huntsman campaign sends along this message about a recent surge in their fundraising:

Our campaign smashed a 24-hour fundraising record yesterday when we raised $112,000+ to help get our new ad “Country First” on the air across New Hampshire. If you haven’t seen the ad yet I encourage you to watch it on our website here.
We can’t stop now. With just hours to go until the polls open in New Hampshire, it is critical that I am able to keep my message on the air!

A strong second-place finish in New Hampshire would bring Huntsman some million-dollar days as well, no?
