An interesting article An Inside Look at How the Iowa Democratic Caucuses Work by Jerald Thomas Hawhee, describes the process. Like many I'm sure, I had dismissed the whole process as some kind of strange, arcane nonsense. Well not for the first time, I think I was wrong! As explained by Hawhee it is really an example of grass roots participatory democracy (remember that word?) in action. It raises some interesting questions for me on the whole of the election process.
