stuff wot I'm reading

The three registered voters in our household each got a folded postcard from our local Board of Elections in a small Massachusetts city. On the outside, one side has the name and address; on the other side, it has a voter confirmation form. On the *inside*, there's the following:

"Dear Voter:
Our records show that you have not answered the annual street listing (census) as required by law (Massachusettes General Law Ch. 51 S. 4). Therefore, your name will be designated as "inactive" on the voting list.
If you have not moved or if you have moved to a new address in the City of Medford, please return the attached postage-paid postcard and you will be restored immediately to active voter status.
If you have moved to another City/Town or State, complete, sign and return the attached postage-paid postcard and your name will be removed from the voter list in Medford. You must register to vote in your new City/Town. You may use a mail-in form or online at www.registertovotema.com to register in Massachusetts .
If you do not return the attached postcard, your name will be removed from the voting list if you do not vote in at least one of the next two federal elections or take other action that would reinstate you as an active voter. (per M. G. L. Ch. 51 S. 37A)"

N.B. - I returned our city census and we have all voted in the last three elections.

So yeah, voter suppression exists even in this very blue state, and they're probably hoping people will ignore this reminder in a local elections year. Check your mail! And you can find out how to check your voter registration in another state at vote.org.
