No, their polls three months out it have always veered leftward. It is true that they may often tone down the bias in their last poll before the election just to preserve a false record of accuracy. However this poll, like all of the other academic political polls in Wisconsin taken before very the end of the campaign, is meant solely to affect the outcome and not predict it.
I'd add that these polls are signals to the rats as to what extent they need to gear up their fraud machines.
