Random thought, but if your sample is coming out to a raw D+31 sample, perhaps there’s something wrong with your pool that you are originally drawing from? Are they just calling people in blue states? Further, if you look at the internals, they only weight the poll to D+9 while the 2020 election was Biden +4. The margin was even smaller in the vote totals for the House, for example. In other words, the country much more evenly divided than shown here, but according to these pollsters, we are in a new era of peace and unity.
