The caucus process is confusing and arcane. It's hard for some people to commit an afternoon. The causcus is also full of energy and humanity, and in many ways shows the democratic process at its best. Neighbors meet and debate and choose representatives from among themselves. As one man at his first caucus told me, the caucus is so much more personal than voting. Nice story about a first-timer's experience here; don't miss the slide show.
The involvement and excitement of young people is inspiring. Two of my precincts five delegates (three Obama and two Clinton) are college students. I've known both of them since grade school. T.'s son decided to go at the last minute and became a delegate. It's wonderful to be a part of the process and just as wonderful to see young people -- the future, after all --become invested in said process. I've been going to caucuses in Texas and Washington since I was 18; I always come away feeling great about this country.
