If a presidential election were held today, President Obama would lose handily. This article in National Journal reports polling data that says fully 50 percent would vote for someone other than Barack Obama, while only 40 percent would vote for him.

I suppose the remaining 10 percent haven't a clue, which if anything seriously understates the true frequency of cluelessness. Two questions I'd like to see polled: How many voted McCain last time but will vote Obama this time? How many voted Obama last time but will vote for someone else this time? I think those numbers would be revealing.
