Chris Bowers has a great in-depth look at where the race stands for the primaries and caucuses over at Open Left. He ends with:
Can either Obama or Clinton beat Huckabee? Yes, but it could be a closer election than we had been expecting. Huckabee locks down the southern Republican base, with the possible exceptions of Virginia and Florida. He is also strong in Ohio. Those are strengths that return us to the tight elections of 2000 and 2004, not the blowout election many of us have been hoping for.
