Several 2026 Senate contests remain exceptionally tight heading into the final weeks, with polling averages placing Iowa, Ohio special, Texas, and Nebraska inside or near a 1-point margin. In Iowa, Democrat Josh Turek and Republican Ashley Hinson trade narrow leads in recent surveys. Ohio’s special election pits Democrat Sherrod Brown against Republican Jon Husted in a race consistently within 2 points. Texas features Democrat James Talarico challenging Republican Ken Paxton in another projected toss-up, while independent Dan Osborn contests Republican Pete Ricketts in Nebraska. These outcomes hinge on late turnout patterns, national political environment, and campaign spending in the closing stretch before November 3.
