I'm just not sure why people are keen to deny the weight of evidence and previous trends. It's a kind of ignorance that makes one no different than the Trumpists. Does the tightening really matter in the grand scheme of things? No. But we still have evidence of it.
We have evidence in aggregate that the polls have probably moved from around Clinton +6.5-7.0 to around Clinton +6.0-6.5. The chance that it's entirely noise is non-negligible. It's likely it's tightening, but I think there are periods where just eyeballing the polls -- instead of adjusting from when they're released, how big they are, etc. -- can give illusory or exaggerated signals. I think this is one of those times.
