The youth bloc that is backing Obama were relatively fickle four years ago when they were backing Dean. It's hard to count on youth in elections. Also, the poll shows that a third of voters may change their mind over the next couple of days. That is the silver lining that leads me to believe we are seeing the "Bradley Effect" in action. We will know Thursday night.
The Bradley effect is pretty small in the first place, even smaller amongst Democrats, and even smaller than that amongst Democrats committed enough to go to the caucus. It won't be an issue.
