Correlation of Early Primaries with Presidential Elections?

[The Curtmudgeon]

Can anyone here point me to a good source for comparing the results of previous Iowa, NH, etc., primaries with the actual election results for those years? My own expectation is that there will be no noticeable correlation at all (over the long haul), but then I'm pretty much an extreme cynic when it comes to politics. I'd like to know, though, if this has been analysed already.

In 1968, Richard Nixon beat George Romney in the New Hampshire Primary and went on to be elected President. Romney was named Secretary of Housing and Urban Development and later resigned in protest over the bombing of Haiphong Harbor.
