Polls are not the only place people look to for guidance to Election Day outcomes. Lots of people believe in bellwethers.
The first two things to know about bellwethers is that there's no letter "a" in the word, and bellwethers don't have anything to do with predicting the weather. The name refers to the neutered rams that shepherds use to guide flocks in the right direction. The wether trots along when the shepherd calls, the bell at his neck jangles, and the other sheep come ambling after him.
