If the margin of victory for Janet Mills in the 2026 Maine Democratic Senate primary falls within 0% to 100%, inclusive of its lower bound and exclusive of its upper bound, then the market resolves to Yes.
The margin of victory shall be calculated as follows based on the margin type.
For percentage points: the vote percentage received by Janet Mills minus the vote percentage received by the candidate/party/option that finishes immediately behind Janet Mills if Janet Mills wins, or the candidate/party that finishes first if Janet Mills loses.
For raw votes: the total votes received by Janet Mills minus the total votes received by the candidate/party/option that finishes immediately behind Janet Mills if Janet Mills wins, or the candidate/party/option that finishes first if Janet Mills loses.
For electoral votes: the electoral votes received by Janet Mills minus the electoral votes received by the candidate/party/option with the second-most electoral votes if Janet Mills wins, or the electoral votes received by Janet Mills minus the electoral votes received by the candidate/party/option with the most electoral votes if Janet Mills does not.
Each margin range is inclusive of its lower bound and exclusive of its upper bound. No rounding shall be applied to the calculated margin. For example, for consecutive ranges of 5-6% and 6-7%, a margin of 5.99999% resolves within the 5-6% range, while a margin of exactly 6% resolves within the 6-7% range. If Janet Mills runs under multiple parties or is listed multiple times, votes attributable to the same underlying natural Janet Mills will be summed.
If Janet Mills wins the election, the margin will be positive. If Janet Mills loses the election, the margin will be negative. If Janet Mills ties for first place, the margin shall be 0. For uncontested races where Janet Mills is the only candidate, the margin shall be 100 percentage points or the total number of votes cast (for raw votes).
