WI-Marquette: Clinton +3

[NOVA Green]

Uhhh, does Marquette even bother to explain a 12-point swing during the most inactive month of the campaign?
I mean maybe Clinton called the Wisconsin voters "dumbasses" and somehow I missed that.

Or did she mispronounce the name of their football field?

So, my main question on this poll and all others conducted within the past week, is this:

How historically do polls conducted the week before the Labor Day weekend, stack up for historical accuracy?

I mean, for many this is the last weekend to head out on family vacations, take the kids out to the lake, etc....

Are there significant historical variances in polls conducted at a time where a huge chunk of voters are out and about before everything changes and it is easier and more realistic to actually contact registered and likely voters that are frequently unavailable during this particular week?
