The closely matched probabilities across multiple turnout ranges for the 2026 West Virginia U.S. Senate election reflect trader uncertainty over participation levels in a low-competition contest. Incumbent Republican Shelley Moore Capito secured her primary nomination decisively, while Democrat Rachel Fetty Anderson emerged from a fragmented field, leaving the general election on November 3 with limited suspense that typically suppresses voter mobilization. West Virginia's rural demographics, historical midterm turnout patterns, and modest registered voter base contribute to the range of projected totals. Party get-out-the-vote efforts, economic and energy policy salience, and any late shifts in national sentiment remain the main variables that could separate the bins before Election Day.
