I still think we will see 5 entirely new polls before the debate. Monmouith has confirmed they will do one and yesterday Chuck Todd said NBC will have a new one out in a couple weeks. CNN tends to poll at the end of the month so that is 3. I suspect that FOX would want their own poll to be one of the five polls so that would be 4. So you just need one more. Quinnipiac is due for a poll, they havent done one since May and McClatchy/Marist hasnt since March. And then there are other live phone pollsters that havent done any this cycle including CBS/NYT and Pew.
I wouldn't be shocked if 5 or more polls are released on the deadline day.
