Our read (Hansen Intel synthesis, not a forecaster's call)

Lean Democratic, still competitive

Markets give Democrats 63–65%. But raters have Democrats at only 47–49 seats leaning their way (51 needed), so they must win most of the 4–7 toss-ups, nearly all in Republican-held states. Cook calls the chamber itself a toss-up and estimates a Democratic gain of 2–6 seats; they need 4.

House218 for control

D 214218 needed · 2 vacant1 I + R 218

Our read (Hansen Intel synthesis, not a forecaster's call)

Democrats favored

All three raters already put Democrats at 212–214 seats at least leaning their way (218 needed) with 18–21 toss-ups, versus 200–205 for Republicans. Prediction markets give Democrats about 90%, and the generic-ballot average is D +8.3.
