How Much Does N.H. Matter?

Thanks to its state law, New Hampshire has the distinction every four years of holding the first-in-the-nation presidential primary election, which gets plenty of attention from candidates and from the media.

But winning there certainly doesn't mean a candidate is destined for the party's nomination. In fact, the last three presidents finished second in the New Hampshire primary.

So just how much does the contest matter? While visiting the Granite State, All Things Considered's Sacha Pfeiffer put that question to University of New Hampshire political history professor Kurk Dorsey.
