How long has this model been around? Obviously, unless Norpoth is the worlds oldest living statistician, he didn’t predict the 1912 election in advance.
So that leads me to wonder if he developed a model last month which fits almost all elections in the last hundred years. It seems to me this would have very little predictive value.
