I was thinking this and TPM Reader JW just wrote in and made the same point. As much as John McCain is winning the Democratic core states, something similar might be said about Obama. Not quite as clear cut. But there’s definitely some of that. So far Obama’s taken Alabama, Delaware, Georgia and Illinois. Take out his home state and that’s two deep south states and one border state.
At the moment, as you can see on the scoreboard on the right, Obama has a razor thin lead with about half the vote counted in Connecticut. If he can pull that out, it’ll be his only state in the Northeast, with Hillary taking New York, New Jersey and Massachusetts.
