Points to YES

Democrats hold a nine-point lead on the generic congressional ballot, a national margin consistent with Republican losses deep enough to approach the threshold.
Silver Bulletin's October 26, 2026 polling average showed Democrats leading the generic congressional ballot by nine points, or 9.5 points with a likely-voter adjustment.
Published simulation ranges extend well below the threshold, with Scrutinel's central range running down to 175 Republican seats and a Woolley model estimate flagging losses above 40 seats as plausible.
Scrutinel's October 28, 2026 simulation put Republicans' 80 percent range between 175 and 215 House seats.
