David Flaherty is CEO of Magellan Strategies, a Colorado public opinion research firm. We'll discuss why so many pollsters got so many races wrong in the midterm elections. For example, on one website I looked at that tracked public polling, only one poll since mid-October had the Democrat winning the Arizona governor's race. And yet she won. Here in Colorado, polls had Republican candidates for Senate and governor down by single digits; instead, they got blown out by 14% and 19%, respectively.
