One of the best things about the night has been the turnout at the caucuses.
Nearly double what it was in 2004, and almost quadruple
(I believe, lazy web prove me wrong) almost triple 2000.
For political insiders and junkies, there is also this: Ann Selzer nailed the polling for the Des Moines Register, especially the predictions/projections for first time caucus-goers and independents. Most pols (especially those working for Hill and Edwards) poo-poohed her methodology. But she nailed it, again. Backstory here.
