Oct. 8, 2018 — The Democrats need to convert a net 24 seats to secure a one-seat majority in the US House on Election Day, Nov. 6. Many reports quote the number 23 as what is necessary to win control, but the new Pennsylvania map will yield one seat coming back to the Republicans — the new open 14th District — thus pushing the total up to 24.
As stated Friday, our forecasts listed below are based upon a series of factors, including current polling numbers, voter history, candidate personal and job approval favorability, fundraising, other races on the state ballot that could drive turnout, and outside issues such as the confirmation vote to for Judge Brett Kavanaugh to become a Supreme Court Justice, which could change the turnout model, etc.
According to our new analysis, the Democrats are on the cusp of converting the requisite number of Republican seats to take a bare majority and seeing their caucus become significantly larger. At this point, the Democratic gain range appears to reach 23 on the low side and 35 at the apex.
Looking at the country by state and region, it appears the Democrats will do well in the Midwest, in particular. The Great Lakes region that delivered President Trump his surprise victory appears to be snapping back to the Democrats in the midterm House races. Michigan looks particularly good for them at both the statewide and district levels.
