UPDATE
One week left, and there was an upswing for Obama since last Monday. Presently his probability of winning is 74.6% (+7.0), with 297 electoral votes (+9).
A natural disaster is headed towards the East Coast. Certainly Romney's focus group is working overtime to determine the best way to criticize how Obama handles the crisis, and especially to howl over the emergency funding. They need to take a delicate approach though, considering North Carolina, Virginia, Ohio and New Hampshire are swing states.
