The polls have been in something of a holding pattern for the past few days, with two distinguishing features.

First, Biden's lead in national polls is very steady. It was 10.4 points a week ago and it's 10.7 points now.

You really have to squint/cherry-pick to see a Trump comeback in the national polls. The IBD/TIPP tracking poll has bounced around a bit in a vaguely pro-Trump direction, I guess. But the other two tracking polls (USC and SurveyMonkey) show a steady/increasing Biden lead.

There's also a lot of non-tracking poll national data, and it's just become very routine to see double-digit leads for Biden, especially in the higher-quality polls.

The other feature: the state polls *aren't* as strong for Biden as the national polls, although there haven't been that many high-quality and/or live-caller state polls lately.

Online and IVR state polls tend not to show that much change since the debate. Maybe they imply that Biden is +8 nationally or so.

Some of the live-caller state polls we do have could be consistent with a larger Biden lead, though, of +10 or thereabouts.

The non-live state polls are a weird mix. Certainly some of the higher-quality online polls (e.g. YouGov or Ipsos) are worth paying attention to, although some of them (especially YouGov) tend to do a lot of weighting in ways that make them very steady relative to other polls.

There are also a lot of quasi-partisan state polls in the form of, say, Trafalgar or InsiderAdvantage on the R-leaning side, or Civiqs and PPP on the D-leaning side. Some of their polls officially get classified as partisan by 538 and some do not, depending on who the sponsor is.

I don't want to paint all of these firms with the same brush. Civiqs is doing good work, I think. But I have to say... with *some* of these firms, it feels like they're very self-conscious about what their numbers say relative to 538/RCP averages and I don't love that.

This interview with Trafalgar Group really worried me, for instance. These are not conventional polling methods and it sounds like they provide a lot of room for subjectivity or frankly confirmation bias in how one constructs a voter universe.

Also worth revisiting the old @Nate_Cohn critique of PPP. Not because PPP is necessarily still up to this, but because it shows how a pollster can be collecting real data but applying dubious assumptions to it rather than letting the data speak for itself. newrepublic.com/article/114682…
