Denied Childers a chance at winning a seat and thus endangered further the party's Senate majority.
You do realize Travis Childers was never going to win anyway?
Far better that they devote their energies to winnable races than go down this rabbit hole.
The odds were not impossible (especially if McDaniel pulled an Akin) and even if Childers had lost, a truly competitive race in Mississippi would have laid the foundations for future Democratic efforts. Indeed, it might force the GOP to devote additional resources to this state.
