Well, you'll have to wait till 2008. Really, this is the only intelligent article I've read about the possibility of predicting the outcome of the '08 elections. Do yourself a favor, and save all of the assured predictions of the outcome, which will, like every election past, make fools of most pundits, except for a couple who have the luck to guess correctly.
No one knows how future elections will turn out, and polls at this point are just a mindless and impotent exercise. Keep that in mind when you read all of these professional predictions.
