| Summary/Abstract |
The Primary Model predicted that Barack Obama would win a narrow victory with 50.1% of the major-party vote. Obama surpassed that forecast by just a little more than one standard error (2.5). How come the model came as close as it did with a forecast issued as early as January? What prevented it from coming even closer? And what might be done to improve the model?
