I wrote a thing about upcoming MA primary; Cambridge specific but other than locations of early voting/dropboxes applies everywhere in the commonwealth: https://letschangecambridge.us/articles/you-can-vote-in-primary/
Independent voter? Moving? You can (and should) still vote in the Sep 1 primary
If you’re a registered voter, you can and should vote in the upcoming primary.
