I believe this means Perry and Kasich are now tied at 1.8 for the 10th spot. The last poll left before the debate is probably Quinnipiac (unless there's a surprise poll). Their last poll had Kasich at 2 and Perry at 1. If Kasich is up 2 to 1 against Perry in their next poll, he will have clinched the 10th spot with 1.8 to Perry's 1.7. Either way, someone will be pretty upset.
PPP are unlikely to be included. FOX is likely going to only use live phone polls (that is the assumption being used by NYTimes, WaPo, 538, NBC news and others). That being said, I suspect there will be 5 live phone polls released before the Fox debate.
