Recent polling averages show Michigan’s open Senate seat between Democrat Abdul El-Sayed and Republican Mike Rogers as highly competitive, with leads typically ranging from one to three points across surveys from Rasmussen, InsiderAdvantage, YouGov, and others conducted in early to mid-October 2026. In contrast, New Hampshire’s open seat pitting Democrat Chris Pappas against Republican John Sununu has produced steadier margins of five to seven points in the same period. These patterns, combined with Michigan’s status as a battleground with narrower historical swings in recent cycles, underpin trader consensus that the Michigan race is more likely to finish with the smaller margin of victory on November 3.
