270toWin Maps 40-Day House Forecast Split as Models Signal Democratic Wave

Forty days before the Nov. 3 midterms, 270toWin published side-by-side House consensus maps showing a clear split between expert race ratings and quantitative models.
Three model-based forecasts argue Democrats' generic-ballot lead and President Trump's weak approval point to a stronger Democratic outlook than traditional handicappers currently show.
Three expert forecasts instead lean more on district-level factors such as candidate quality, fundraising and internal polling, producing a less bullish map for Democrats.
The comparison uses the most common district rating across three forecasts in each camp, based on Sept. 23 data, and 270toWin said the two pictures will likely converge somewhat before Election Day.
