John Sides is doing yeoman’s work at The Monkey Cage debunking myths about the Iowa caucus and the primary process. Here are two of the most interesting posts:

1. New Hampshire doesn’t have a better track record than Iowa of predicting the eventual nominee.

2. Democratic and Republican primary voters are not substantially different than Democratic and Republican general election voters according to a Forum article by Alan Abramowitz (PDF).

He also highlights a series of misconceptions from a Forum article by Peverill Squire (PDF).

Update 1/4 10:11 PM: To clarify, claim #2 is that primary voters are not substantially ideologically different from general election voters — as Rob correctly notes in a comment, the Iowa and NH electorates are absurdly unrepresentative of the nation’s demographic composition.
