I'll admit that the oversampling involved seems to achieve the desired result, without being at all accurate. In retrospect, I'm not sure how anyone could conduct a poll with weighting several points over actual turnout in 2008 and be considered accurate. Actual voter turnout proves that they weren't.
The thing I'm at a loss to explain is voter enthusiasm levels. It surprises me to see that Republican turnout was lower than expected and that Democratic turnout was higher. These are not facts which could have been anticipated in the months leading up to the election.
Regardless, enjoy your gloat while you can. Remember a stopped clock is correct twice a day.
