I would love an Obama-Huckabee race.
Yes, would be interesting. I could see something like this happening in the case of Obama vs. Huckabee:
Whoever wins 2 out of the 3 deciding states in the West will be President.
It may very well come down to Colorado next year. The senate race there will most likely be a Dem victory, which may help push the state into the Dem column...with Obama, but not if Hillary is the nominee. Virginia could also be interesting, but Huckabee would win between 3-4%.
Also, I think IA should be "green" on your map...remember that it switched from Gore to Bush.
Iowa probably goes Dem. There's been a lot of backlash against the GOP there, just not quite to the extent as say, NH. And I agree, Ohio doesn't really like Obama so that would make the race come down to Colorado, wouldn't it? Colorado is a good state for Obama though as is Nevada and New Mexico. 2008 could be the year the West comes into play. Aww yeah.
