Beware national generic ballot numbers. They are impacted by wide margins for Democrats in certain Congressional districts in California and New York. The only thing that really matters is a district by district analysis.
Not entirely true. To a large extent, a rising tide lists all boats. We used to be able to predict what numbers the democrats need in a reliable national poll to flip various close elections. What we can no longer do is tell how reliable polls are. Even the honest ones have an increasing level of conservatives refusing to respond at all and of conservatives who do respond being reluctant to reply honestly in areas where leftist bullying has intimidated them into silence. They still vote for freedom, but they do it quietly.
