The following table indicates the party of elected officials in Massachusetts:

• Governor
• Lieutenant Governor
• Secretary of the Commonwealth
• Attorney General
• Treasurer and Receiver-General
• Auditor

The table also indicates the historical party composition in the:

• Massachusetts Senate
• Massachusetts House of Representatives
• State delegation to the United States Senate
• State delegation to the United States House of Representatives

For years in which a United States presidential election was held, the table indicates which party's nominees received the state's electoral votes, and whether they Y won the election or N lost the election.

Each time an official is elected or re-elected, a new box for that official is included to indicate their repeated political party strength.
