Municipal Elections in
Elections for nine members of the Council and six members of the School Committee are held in November in odd-numbered years.
Under PR, any group that numbers more than one-tenth of the voters may elect at least one member of the City Council.
Any group that numbers more than one-seventh of the voters may elect a member of the School Committee.
The mayor is elected by the City Council from among its own members and acts as chair both of that body and of the School Committee.
Proportional Representation (PR)
A voter may vote for as many candidates as are listed on the ballot in a PR election, but the voter must rank the candidates in order of preference (1, 2, 3, and so on).
If the voter's 1st choice is not elected, a 2nd, 3rd, or subsequent preference may still be elected by that voter's ballot.
The voter also has the option of voting for only one candidate, or for as few as are preferred.
Marking the Ballot
The PR ballot lists candidates with numbered ovals next to their names.
To vote for a candidate, the voter fills in one oval only next to the candidate's name: 1 for first choice, 2 for second choice, 3 for third choice, and so on.
Example: Correct Marking
Candidates' names are rotated on ballots so that each candidate's name appears at the top of the ballot an equal number of times.
Example: Invalid Votes for Candidates
Filling in more than one choice for a candidate
Filling in the same choice for more than one candidate
Votes may also be invalidated by marking ovals incorrectly, so that they cannot be read by the optical scanner.
Example: Incorrect Marking of Ovals
If a mistake is made in marking the ballot, the voter may return it to the election official in charge and receive another one, but no voter may receive more than two such new ballots.
Counting the Ballots
Tabulation of PR ballots begins with the sorting and tallying of first choice votes for each candidate and the establishment of quota, the minimum number of votes sufficient for election.
It continues with the transfer of surplus and the redistribution of votes from defeated candidates to continuing candidates until nine Councilors and six School Committee members are elected.
Quota is established after the count of first choices.
Quota is determined by dividing the total number of valid ballots by the number of candidates to be elected plus one and adding one to the result.
Example: If 25,000 valid ballots are cast for City Council, the quota will be 2,501 (25,000 divided by 10, plus 1).
Example: If Candidate A receives 3000 first choice votes and quota is 2501 votes, Candidate A is elected with a surplus of 499 votes.
A formula determines which ballots are selected to be counted as surplus.
Surplus votes are transferred to the second choice candidates on the surplus ballots.
After surplus votes are transferred, candidates who have fewer than fifty number one (#1) votes are eliminated.
Their votes are transferred to the continuing candidates marked next in preference on those ballots.
After each transfer of ballots from a candidate being counted out to continuing candidates, a new ranking is established.
The candidate with the lowest number of votes is declared defeated and that candidate's ballots are transferred to the next continuing candidate marked on each ballot.
Transferred ballots are added to the totals of the continuing candidates until they reach quota or are counted out. After a candidate reaches quota and is declared elected, no more ballots are transferred to that candidate.
Computerized Ballot Tabulation
In 1997 the Election Commission computerized the City of Cambridge PR elections using a precinct-based optical scanning system and specially designed software.
Tabulating the Votes
The PR Count, which used to be performed manually during the course of a week by a staff of over a hundred, is now completed in a matter of minutes through the electronic sorting, counting, and transfer of votes.
Unofficial results for City Council and School Committee are available on election night. These results are "unofficial" because not all ballots have been counted.
The tabulation does not include ballots with write-ins or ballots marked in a way that could not be read by the scanner. These are auxiliary ballots which must be processed manually and added to the computer totals.
On the day after the election, votes from write-in and auxiliary ballots are added to the totals from the previous night.
The complete ballot records are tabulated, without reference to the earlier tabulation of unofficial totals, to produce the official first choices.
Next, the software distributes surplus ballots, transfers votes, and eliminates candidates until the number of seats for each office has been filled.
Since 2005, according to state law, official results are not finalized until 10 days after the Election, when any Provisional Ballots and/ or Overseas Absentee Ballots have been counted.
