Westword just put up a story about the Colorado Caucus, I put up link to it on Facebook.
Writer John Skipper just posted this there:

"The caucus system is the essence of democracy - grassroots, door-to-door, living room-to-living room campaigning followed by the actual caucus where anyone can stand up and tell their views on issues and candidates - followed by a public vote. You can't beat it. I ought to know. I'm from Iowa. In fact, I've just written a book about the Iowa caucuses and have a Web page that will tell you all about it.

I've read John Skipper's book The Iowa Caucus, and it is excellent. I encourage everyone who cares about the caucus-assembly system as a way to strengthen the grassroots to have it on their book shelf.
