Finally, we get to the good stuff. Liddy Dole was once considered bulletproof, but she's been running consistently behind Kay Hagan and figures to be on her way out. It's not totally clear why Dole is vulnerable; she's a heavy hitter and has always been fairly popular in North Carolina, but her approval ratings have been declining this year and she hasn't cracked 50% approval in a while.
If McCain manages to right the ship and win NC by a large margin, Dole might be able to come back. But as of now she looks like she's done.
