One thing people don't get re: the 15% viability threshold in Iowa caucuses is that if you don't initially get 15% in your precinct, you're *not* necessarily screwed. Rather, you can try to peel off support from other candidates who don't have 15% to become viable. https://t.co/2hedPVBHpE — PolitiTweet.org
