So many Biden +8 (or +7/+9) polls, which "coincidentally" is exactly the margin by which Democrats won the House popular vote in 2018. For all the "But 2018 was a D+8 year!1!" talk, it sure doesn’t look like the national environment has improved for Republicans since that election.
Also, the 538 aggregate has Democrats winning the House popular vote by... exactly 8 points (48.4%-40.4%).
This is a far more static election than people think.
That's the conclusion to which I am coming as well. If you want to see what 2020 will look like? Just look at 2018 and its trends.
