Last month, over at MyDD diarist fladem looked into the historical impact of the results of the Iowa caucus on the results of the New Hampshire primary. His or her study was a useful one, since it provides us with a general framework for how much a 1st, 2nd, 3rd or even 4th place finish in Iowa will impact New Hampshire standings. Using immediately pre-Iowa polling in New Hampshire from 1988 and 2004, the last two times Iowa was hotly contested in the Democratic primary, fladem produced the following estimated New Hampshire bounce for Iowa:
Iowa impact on New Hampshire
1st: Plus 14.5 in NH
2nd: Plus 3.2 in NH
3rd: Minus 3.5 in NH
4th: Minus 4.4 in NH
These numbers pretty much jibe with what I have heard about the historical Iowa bounce, so for the purposes of this post I am willing to accept them. Also, according to Pollster.com, here are the current estimated standings in New Hampshire:
Now, even without these numbers, it is generally accepted that if Clinton wins Iowa, she will have little difficult sweeping to the nomination. However, in the extended entry, using the numbers above, I have provided estimated results for every other New Hampshire scenario involving a top four Iowa finish among Clinton, Edwards, Obama and Richardson. Check it out:

Analysis: Obama wins in New Hampshire in four of the six scenarios, but every scenario is within four points. All very close. Also, an Obama victory instantly makes the campaign a two-way race between him and Clinton.

Analysis: With the possible exception of Richardson #4, the most interesting of all New Hampshire scenarios is Edwards #4. However, as we will also see with Richardson below, Edwards fails to take the lead in any possible Iowa scenario. The conclusion must be that Edwards needs to improve in New Hampshire, and at least hold his current lead in Iowa, to have a real shot at the nomination, since he probably needs to win both states in order to make up enough ground elsewhere.

Analysis: Since he leads in none of these scenarios, Richardson is probably not yet close enough in New Hampshire yet to have a shot at the nomination. Currently, he probably has to win both states to take the nomination. #1 is the best scenario for Richardson, but even it probably isn’t enough to take New Hampshire (yet).
Overall: Clinton’s advantage in New Hampshire is currently so strong that it appears she has a more than reasonable chance to win the state even after a third or fourth place finish in Iowa. In fact, while several other scenarios are quite close, she is currently projected to win the state in every scenario, except for a third or fourth place Iowa finish combined with an Obama Iowa victory. Thus, it would appear that as long as she maintains either a lead of at least 11-12 points in New Hampshire, or at least second-place in Iowa, she must be considered the prohibitive favorite for the nomination. Of course, we are still about five months of the Iowa caucus, so a lot can happen between now and then.
