They know the voter's state and even an approximation of congressional district, based on zip code. It would be interesting to see the cross-tabs for the individual states. But, I don't know if they publish that data, even to subscribers.
I saw one where the beast was up by 2. I looked at the internals. They listed the states. North Carolina, New York, Maryland, Minnesota and two others that we both deep blue. Only NC was reasonably within the red realm. They oversampled women 64-36. They oversampled Democrats 36-24-30-10 The 10 are Libertarians and Greens.
Another, they did 0 Independent, 0 Lib/Green, 57-43 Dem/Rep. She was up 7.
They’re not even trying to hid their propaganda this cycle. It’s not news, but propaganda. Don’t believe the lying polls.
