I sure hope not, but worth consideration.
This election isn't over yet and I'm not backing off my plan to A) Vote, and B) Personally goad and follow up with at least 2 people I suspect might not bother to vote to make sure they do, even if it means I have to pick them up and we go together. Hillary only of course :p
Don't believe the math because it isn't truthy enough?
The linked article explaining the truthiness is talking exclusively about post-convention bounces, not noise, not reversion to the mean, not all the polls, not all the statistics.
With that said, it’s not the massive polling miss that would concern me if I were Clinton. Instead, I’d worry about what might happen if Trump was on a rising trajectory as Nov. 8 approaches, having cut my lead down to 3 or 4 percentage points, and then there was a more modest polling error on the order of what we saw in advance of Brexit, where the final polls were off by about 4 points. Polling errors of that magnitude are considerably more common than 6- or 7-point errors.
