**Dems sweep leads at 69% because polling averages and forecasts show Democratic nominees holding consistent edges in all three open-seat races three weeks before Election Day.** In Michigan, Abdul El-Sayed maintains a roughly 3-point lead over Mike Rogers across dozens of polls, supporting Lean Democratic or Likely Democratic ratings. Minnesota’s contest between Peggy Flanagan and Michele Tafoya has tightened into a Lean Democratic race, with Flanagan ahead by about 3–4 points amid heavy Republican focus on the open seat. New Hampshire’s Chris Pappas holds a stronger 5–7 point advantage over John E. Sununu. These margins, combined with the states’ recent voting patterns and fundraising disparities favoring Democrats in New Hampshire and Michigan, underpin the trader consensus on a full sweep. The next-most-likely outcome—Republicans taking only Michigan while Democrats hold Minnesota and New Hampshire—trades at 20.8%, reflecting Michigan’s relative closeness.
