This map can't be the outcome of all the elections.
Senator Burr is actually a good friend of my father and his girlfriend. She's very close with his wife, and Richard and I attended the same college.
Anyway, I can tell you Burr was in the running for a while for the VP and is very popular in North Carolina and in Washington. Whether that means he'll run for President in the future remains to be seen. He'll need to defeat the curse that has plagued the seat he occupies for a while.
But the map all depends on how Obama does as President. I doubt either McCain or Obama will have a successful term considering how bad things are worldwide right now.
Assuming Obama has a weak first term and really does nothing memorable, I bet we see this in 2012. Keep in mind if McCain has the same mediocre term that Obama has, which he very well could, it would be a landslide in the other direction. With the war over by 2012, I think we could be in for a reallignment in which many of the Northeastern Industrial states move toward the GOP while the west becomes more Democrat. I don't think the current map trends we see now will hold up much longer as issues change.
New Mexico is a tossup as always as Burr is very pro-immigration. But really, it all depends on how Obama fares in his first term as to whether Burr can actually win.
