Wasn't there a national poll earlier this year that PPP ended up never releasing?
They've actually done that twice now. There was the one in June that we discussed here:
https://uselectionatlas.org/FORUM/index.php?topic=175579.0Both Tender Branson and I asked them about this one in blog comments and/or Twitter, but they ignored our questions.
Then last week, they mentioned that they did a national poll the preceeding week but weren't going to release it because "it is kind of dated now":
