@petermarksdrama Slightly oversimplifying: You need roughly the same sample size in a poll to survey NH as you do to poll America. So at, say, $50,000 a poll (a current estimate), separate surveys of IA, NH and SC would cost $150,000. Plus a national poll sounds so much more dramatic. — PolitiTweet.org
