The tightly clustered probabilities across turnout ranges reflect substantial uncertainty over voter participation in West Virginia's November 3, 2026, Senate contest between incumbent Republican Shelley Moore Capito and Democrat Rachel Fetty Anderson. A low-competition race in a solidly Republican state tends to limit get-out-the-vote efforts and overall engagement, while historical midterm patterns, rural demographics, and weather on Election Day introduce additional variability. The May primaries recorded notably higher early voting than 2022, yet that momentum has not translated into clear signals for general election totals. Traders appear to weigh these offsetting factors evenly, with any late shifts in campaign intensity, national political environment, or registration trends potentially widening spreads.
