Iowa has caucuses rather than primaries, and from what I hear from my family, that's essentially how the Democratic party caucuses work in Des Moines, Iowa. Rather than filing in and filling out a ballot, my father describes the process as going into a room, forming groups around candidates, and then trying to convince the uncommitted to support your candidate. It always sounded like a rip-roaring good time; now it's interesting to learn that this process might produce better results.
