Quick nugget... Polling suggests (at this point) that at most 12 or 13% of Moore voters have changed their mind. That's enough to potentially change the outcome, but difficult to pick up outside of polling.
Doesn't normally the reaction to news like this take more than a day or two to really matter in polls? Just anecdotally it seems most October type surprises took a few days to make an impression. But it's not out of the question that this is wishful thinking.
