Bill Bishop, author of the The Big Sort, has a new blog up on Slate, with his first two posts focused on why the electoral map will essentially remain the same, despite the 50 State Strategy:

Sen. Obama is stuck. He didn’t find a way across the boundaries of lifestyle and culture that split Democrats. And now it’s the middle of September and he still trying to find a way to bring these very different Americas together. (It might be there isn’t one.)

John McCain may have come to another conclusion: That he doesn’t need to widen his net and can win by turning out the same voters who elected Bush.
