- The "margin of victory" is defined as the absolute difference between the percentages of valid votes received by the first-place and second-place candidates.
- Percentages of the valid votes received by each candidate will be determined by dividing the total number of valid votes each of the top two candidates receives by the sum of all valid votes cast in the election.
- For purposes of this market, candidates nominated by the Democratic & Republican Parties will represent the options for "Democrat" and "Republican," respectively.
- Independent candidates will not represent options for either party.
