re: #52 The Mongoose
I suppose they could have included both but I can see their justification for going either way. The average polling date of the 3-day was more recent than the average of the 7-day. Anyways it’s all washed away now.
By that justification, the average polling date of the 3 day snap shot is still more recent than (or just as recent as) today’s poll. It still includes two pre-debate days.
