@rawatersjr @kausmickey It's even worse than that. Roughly 140,000 Democrats participated in the caucuses in 2004, 240,000 Democrats in 2008 and 180,000 in 2016. Nobody knows the next number in that sequence. And it is impossible to have a meaningful poll if you have no idea who will turn out. — PolitiTweet.org
