That's really no surprise, given the sizable margin John McCain has there, but it comes with the recognition that Barack doesn't have the financial edge perhaps he expected; both sides have about the same amount of money to spend. Barack recently pulled out of Georgia, as well (Alaska, too, for obvious reasons).
For Obama, that's three states down, 54 to go . . .
Even so, it's not as though North Dakota is a hard-red state, or anything. Both senators (Dorgan and Conrad) are Democrats.
