Kay Barnes, the former mayor of Kansas City, was one of the first top-tier recruits by the DCCC in 2007, so this is a genuinely painful polling result to see. I've heard whispers in recent days about internal polling also saying that this race has slipped away, and indeed, the DCCC hasn't made any significant expenditures here in nearly two weeks (although the NRCC is continuing to pour it on, so at least Barnes is doing other candidates a favor by drawing some enemy fire).
Tough breaks -- but perhaps this should serve as a reminder for next Tuesday that we can't win 'em all.
