- John Hurd70% (7 of 10)
- Stephen DeCourcey60% (6 of 10)
- Len Diggins20% (2 of 10)
How these numbers work
- Counted from the official minutes, for 2020–2021 Board only. Committee meetings and routine votes (adjourning, approving minutes) are not counted.
- Attendance counts the meetings where the minutes list Mahon as present or absent at the start.
- Only votes the minutes record member by member are counted. Voice votes and votes given only as a count (for example 6-3 with no names) are not.
- Percentages are shown only when there are at least 10 meetings or votes to count.
- A split vote is one where at least one member voted yes and another voted no. “In the minority” means on the side with fewer votes; ties are not counted.
- “Whole board” combines every member’s record for the same term.
These numbers describe the record; they are not a grade. A no vote, an abstention or a minority vote is neither good nor bad. MassVoter never rates officials.
