The contract that resolves to Yes shall be that which identifies the number of seats in the United States Senate held by the Republican Party following the 2026 midterm elections.
The number of seats that a party holds following the 2026 midterm elections will be the sum of the following: i) the number of U.S. Senate seats won in the 2026 midterm elections by candidates with a ballot-listed or otherwise readily identifiable affiliation of that party, and ii) the number of incumbent Senate seats not subject to re-election or special election in 2026 held by members of that party's caucus.
