There's a good chance that the remaining Deep South Democratic legislatures will fall pretty soon.

I would shift TN and OK to the Blue collumn. IN, OH, PA, MI might fall under complete GOP control as well depending on whether Republican Governor victories can bring in an all GOP legislature. AL might fall, but I am not sure if it will happen in 2010.
If I had to guess, Indiana will be blue after the 2010 elections. We have an overwhelming lead in the Senate, and we barely trail the Democrats in the House. I know of at least one district that will flip, mine, and since 2010 will be much more Republican-friendly, especially in Indiana where Daniels has very high approval ratings, I expect us to control everything.
