Massachusetts launched its automatic voter registration system on Wednesday.
The new system will automatically update a person's voter registration when that person notifies a state agency like the Registry of Motor Vehicles of a new address or other change in status.
Those automatically registered to vote will then be notified by mail of the opportunity to choose a political party or to decline to register.
Republican Gov. Charlie Baker signed a bill approving the system last year so that automatic voter registration would begin in time for the next presidential primaries.
