University of Colorado political science professor Dr. Michael Berry reports that the CU popular vote predictive model has a 100% accuracy rate for predicting the popular vote winner of every presidential election since 1980.
Berry says only four times in the nation's history has the winner of the popular vote not won the election, the most recent being in 2000. In other words, 2000 was the only one of the past eight elections where they did not also predict the winner of the presidency.
The CU model gives a 77% probability that Mitt Romney will win the popular vote in early November. See the Campus Reform article for details. BTW, we first wrote of this model and its prediction for Romney on August 23 of this year.
