Yeah, this is NOT a straight PPP poll and should be reported accordingly. It's akin to an internal if it was done on behalf of the Democrats. The thread should start PPP (D). There's really nothing to see here.
It may have been paid for by a Democratic client, but that doesn't mean they're just going to make it 5 points more Dem just because of that fact. They released the crosstabs and everything as if it's a poll not paid for by a client. I'm not sure about this, but I believe PPP releases all polls they do. We normally only hear about internal partisan polls when they're good for one side.
In any case, this result is about where the 538 Nowcast had SC.
