READING – Town Clerk Laura Gemme over the weekend revealed that her office will soon be sending mail-in primary ballots to voters who requested them. Meanwhile, local citizens interested in casting early votes in advance of the official Sept. 1 primary election can start doing so starting this coming Saturday.

“September 1 primary ballots are here and in the process of being sent to those that requested one,” Gemme noted in a social media message on Sunday, when she also appraised town residents that primary ballots will be color-coded to differentiate political party affiliations and the type of ballot being cast.

Voters during the upcoming primaries will select the final slate of candidates who will face off during state elections on Nov. 3.

Reading residents on Sept. 1 will have the opportunity to pick their Democratic or Republican Party candidates of choice to advance to the final state election. Notably, voters who have registered their party affiliations are limited to casting ballots involving their respective Democratic or Republican Party tickets, but independent or unenrolled voters can select either ballot.

Besides filling various state and federal offices, voters during the general election in November will also decide a record-high number of ballot questions (nine such referendums are to be featured).

The Sept. 1 Democratic Party primary will feature several contested races, including:

• A US Senate seat contest between incumbent Edward Markey and Congressman Seth Moulton;

• A five-way race for the congressional seat being vacated by Moulton between Middleton’s Bethany Andres-Beck, Lynnfield’s John Beccia III, Topsfield’s Jamie Belsito, Andover’s Dan Koh, Salem’s Mariah Lancaster, and Andover’s Tram Nguyen;

• A contest for the state’s Sixth District Governor’s council seat between incumbent Terrence Kennedy and Marblehead’s Diann Mary Baylis;

• A three-way state senate seat race between Melrose State Rep. Kate Lipper Garabedian, Malden City Councilor Carey McDonald, and Malden City Councilor Ryan O’Malley (incumbent Jason Lewis is not seeking re-election);

• and a contest for the 13th Middlesex District state representative seat between incumbent Richard Haggerty and Reading resident Jadon Wilson.

The Republican primary ballot includes just one contested race between Hamilton resident Michael Roger Minogue and Barnstable’s Brian Shortsleeve to become their party’s pick to run against incumbent Massachusetts Governor Maura Healey in November.
