If you know something about the history of the Iowa caucuses, you know three things:
1. Most people don’t really make up their minds until the last month, and often until the last week. Just before the 2016 caucuses, I wrote a post here called “Front runners beware,” which turned out to be fairly accurate.
2. But. BUT. – Iowa caucus polls are consumed like some sort of smartphone app you just can’t put down. You know it isn’t good for you. BUT it HAS to mean something, right? Isn’t the best prediction of what people do in elections is what they say the will do know.
3. And when it is the Des Moines Register poll, people listen. It’s a bit like the old Merrill Lynch television commercial: When Ann Selzer talks, people REALLY listen.
