To my surprise and amusement, Dave Barry is covering the Iowa caucus. Barry's three columns enlighten as well as entertain.
Many bloggers are making their own predictions, including Ben, Xlrq, Antioch Road, The Yin Blog, Cornfield Commentary, and Polipundit. Slate's Kaus then explains why the numbers you hear tonight will be an undemocratic result while Kos believes any margin of victory by Dean will be a great victory.
Poliblog found a story that Edwards and Kucinich have agreed to support each other if either of them do not have enough supporters to be viable. (One of the oddities of the Iowa caucus is that votes from supporters of non-viable candidates do not count, so delegates may change camps throughout the process). I suspect this deal will help Edwards, but it was a clever move for both of them.
