3 months ago Marist said they weren't going to do primary polling because they didn't want to be part of the debate criteria, which they felt was inappropriate.
http://www.politico.com/blogs/media/2015/08/marist-suspends-gop-polling-ahead-of-fox-debate-211675Maybe they timed this poll to come out too late for the FOX Biz criteria and too early to be factored into the criteria for the CNN December debate
BTW, they have a point. If Fox Biz used this poll then it would change their debate. Christie and Huckabee would be on the main stage and Pataki would be at the Kiddie table and Carson would get the #1 podium.
