Democrats hold a consistent 8- to 12-point lead on the generic congressional ballot in recent polling averages, driven by President Trump’s sub-40 percent approval ratings, voter concerns over inflation and the Iran conflict, and strong Democratic showings in battleground Senate races such as Texas, Ohio, Kansas, and Michigan. Forecasting models from Nate Silver, Cook Political Report, and others assign Democrats an 80-94 percent chance of House control and 55-75 percent odds for the Senate, reflecting these trends and limited competitive seats after redistricting. Traders have priced Democrats sweeping both chambers as the leading outcome at 61.5 percent, with a divided Congress—Republican Senate and Democratic House—next at 28.5 percent, as the national environment favors gains for the opposition party less than four weeks before Election Day.
