Cohn should be given the benefit of the doubt here. He did miss in Texas in 2018, but given how intelligent and transparent NYT/Siena has been previously about methodology, I'd have to think they would've tried to resolve their SW polling issue.
Either way, it seems ridiculous to constantly criticize an A+ pollster because you don't like their results. And then turn around and use a 25 LV subsample of Collin County to disprove the rest of their poll.
Nate's rather defensive though. He should be owning the 2018 mistakes but also saying this could be a mistake too. Instead hes pointing to NV and AZ polls that are "good for Biden, so we're probably not wrong!!!"
