I think Webb is going to pull this out in a real nail-bitter.
Clearly the exit poll was wrong.
Looks like a recount no matter what.
As of this time, I have no Idea about MO.
UPDATE: (1:40AM) Webb now leads by 12,000 votes and counting. Those numbers will prevent a state funded recount and likely a big enough margin to survive any recount. So, Allen will have to think long and hard about paying for a recount he can't win.
