I think Stephanie Herseth Sandlin’s finished
From Unlikely Voter: At-Large House races may get a disproportionate amount of attention and polling, but it is what it is. So Stephanie Herseth Sandlin’s polling troubles get the whole country’s attention, while a House incumbent in some other state might barely draw notice. And the South Dakota At-Large Representative is having serious problems. I just don’t see how she can win this.
