Texas Senate race dynamics center on the tight contest between Republican Ken Paxton and Democrat James Talarico, with recent September 2026 polls showing margins of one to three points or statistical ties amid substantial outside spending and Paxton's primary victory over incumbent John Cornyn. Nebraska's matchup between Republican Pete Ricketts and independent Dan Osborn registers slightly wider gaps in most aggregates, though both remain among the cycle's more competitive Republican-held seats given historical overperformance by challengers and shifting national conditions. Forecasters rate Texas as a toss-up or lean Republican while viewing Nebraska as likely or lean Republican, reflecting Texas's narrower polling averages and greater uncertainty heading into the final weeks.
