About

Massachusetts Democratic Senate primary: Ed Markey vote percent? The percentage is calculated as (total votes received by the specified person/party ÷ total valid votes cast) × 100, rounded to the specified decimal places. Resolution is based on certified/official results only, not preliminary results. Write-in votes are included if they appear in certified results. Invalid, spoiled, or rejected ballots are excluded from both numerator and denominator. If multiple rounds of voting occur (e.g., ranked choice voting), the percentage is based on the specified round or the first round if not specified. If the election is cancelled, postponed beyond the market expiration, or no certified results are available by expiration, the market resolves to No. If a recount changes the certified percentage before expiration, the most recent certified percentage is used.
