| Here is what history teaches about the current state of the race: it is far from over. After the diary about Iowa and New Hampshire, I wrote another diary about how New Hampshire changed National Polling. On average, it found that when a front-runner loses New Hampshire, there is a 33-point swing in National Polling. Since that time I have done more detailed analysis that shows when you include GOP contests since 1980, the average is 34.
But the data also shows something else: This bounce is reversible. In at least three instances (1984, 1992 and 1996) the bounce from New Hampshire substantially receded about 3 weeks after New Hampshire. The reasons for this are complex, and I will write more about this tomorrow.
But here is the key point I want to make: This race will not be over when Obama wins NH tomorrow. The people who are writing that are the same people who told you this summer that Clinton had the race sewn up. In short, this is another example of a press that does NOT UNDERSTAND THE PRIMARY PROCESS.
Back to my diary on Iowa and New Hampshire. I wrote this diary in June, entitled how Iowa effects New Hampshire. The key part of that diary is this table, which summarizes the bounce from Iowa to New Hampshire.

How is my prediction fairing thus far? The table below summarizes the results (I am using the realclearpolitics average for the post Iowa number, and the average of three polls taken right before Iowa - Zogby, ARG and Suffolk).

The net swing between Clinton and Obama right now is 16.46 (my model predicted a swing of 19). Pretty Good. BTW, in the June diary I predicted the following if Obama won, Edwards finished second, and Clinton finished third:
Obama 35, Clinton 30.7, Edwards 20.2.
The current realclearpolitics average is Obama 36.9, Clinton 29.1, Edwards 18.8
As I mentioned above, I have conducted additional research how National Polling is effected by Iowa. The updated table, which I will discuss tomorrow, is below:
This table summarizes how various finishes impact National Polling

This table summarizes the impact depending on whether the front-runner won or lost New Hampshire

What I found really interesting in my additional research was how similar bounces from New Hampshire for GOP candidates are to bounces for Democratic candidates out of New Hampshire. |
