Two things:
- This is partially pre-Comey. I'd like to see the swing between the two periods if they have it.
- Even pre-Comey, this would have looked like an outlier. Outliers aren't worthless, though - especially in a State with lots of polls, throw them in the average and you'll tend to get a more accurate result.
Well, your reaction to this outlier was certainly more sane and measured than your reaction to the other one, LOL.
I tend to react calmly to good news and more anxiously to bad news. It's part of a "better safe than sorry" mentality.
