Somebody needs to be ready to run against Jon Bruning.
The Republicans didn't have the time or the will to run someone stronger than Schlesinger in Connecticut last year. The Democrats in Nebraska next year have a lot more options. If as you say Hagel is a pretty standard Republican except on Iraq, that means Hagel is going to lose the primary solely over his stance on an issue where Hagel is more in-step with the public in Nebraska than his replacement is. Couldn't this be a pretty serious opening for the Democrats? What could be done here?
