Looks right, although I'm not sure why Minner's seat is considered safer than Easley's. (I'd put NC at Safe and Delaware at Likely.)
I'm pretty sure an open seat in North Carolina shouldn't be labeled as "Safe Democrat." I agree with you about moving DE back to the likely Democrat category -- Republicans did surprisingly well there in 2004.
I do wonder where Blunt's approvals will be in eight months. His numbers have been recovering lately to the point where they're "not that bad."
Also, Barbour's seat should be listed as "Likely Dem Pickup," because Eaves is resonating with the voters and Barbour is a down dirty Rethug. That is all.
