The map above, prepared by the ever industrious and civic-spirited Frank Burthart (who's pretty damn kick-ass, too), demonstrates a thing or two about the turnout two years ago for the 2005 local Democratic caucuses and convention.
Frank has a good post on the subject as the 2007 caucuses and convention near. Its title? "An Experiment in Political Anarchy".
This blessed offering is concomitant with a primer on local Democratic reorganization from the slimmed-down barrister-to-be David Holt. Called "The Hitchhiker's Guide to the Local Party Convention," it is just that. (Scroll down to find the title; you'll be glad you did.)
