Most forecasts aren't predicting a dichotomous variable. Also it humorously mentions the very rule that will be broken in the next election -- in other words the overfit model is gauranteed wrong the whole time, making it a perfect predictor of the future. Most overfit models aren't based on 1 erroneous variable that can be tested for being extraneous- it's usually based on too many variables in the model, haphazardly all thrown in to reduce R^2. | |
