Did Hurricane Sandy Kill Romney's Chances?

We're one day out, and Nate Silver's Five Thirty Eight blog currently has President Obama as an 86% favorite.  The national media is also beginning to trend toward a close Obama victory.  A new narrative that is emerging is whether or not Superstorm Sandy played a role in bringing a halt to Romney's momentum, or whether it had already eroded.  Silver has been saying for quite some time Romney's momentum had disappeared, but he examines the topic in a post on his blog today.  Check it out (in Silver's post or elsewhere), and let us know what you think.
