The Land campaign apparently called this poll an outlier. In order to consider this poll an outlier one must be using some fuzzy (at best) math. The σ of the polling margins in my aggregate is 4.5%.
While I will not go into the specifics of how to calculate these numbers (too tired to give a stats lesson tonight); a mild outlier would be anything outside of the range R +5.5 and D +14.5. The polling margin for this poll is both within that range, as well as within 2σ of the mean. Therefore, in my aggregate, this poll is not an outlier. If we go back even further than my aggregate and use all polls since July 1st, the range then becomes R +8 and D +16.
