NORTH READING — Labor Day not only marks the unofficial end to summer, this year it also kicks off the official start of the midterm election season.

Voters from all four precincts will cast their ballots in the State Primary Election in the parish hall of St. Theresa’s Church, 51 Winter St., on Tuesday, September 6. The polls are open from 7 a.m.– 8 p.m.

In addition to voting on Election Day, two more days remain in the Early Voting schedule statewide. In North Reading, the remaining sessions are today, (Thursday, Sept. 1) from 8 a.m. to 8 p.m., and tomorrow (Friday, Sept. 2) from 8 a.m. to 5 p.m. These sessions are held in the gymnasium at Town Hall 235 North St.

Town Clerk Susan Duplin told the Transcript on Wednesday morning that 1,803 voters had returned their mail-in/absentee voting applications for the State Primary by the application deadline this past Monday, Aug. 29. She said it was important to keep in mind that these applications provided voters with the option to choose to receive the Nov. 8 state election ballot as well as the Sept. 6 state primary ballot, therefore voters who normally do not vote in primaries may have helped to boost that number.

Each early voting session, which began statewide last Saturday, Aug. 27, has averaged about 20 voters per day, Duplin said. There are three poll workers stationed in the gymnasium for each session, two at check-in and one at check-out. The poll worker at the check-out station also ensures the voter has signed the outside of the envelope of her or his ballot. She applauded the poll workers for their efforts, noting that the gymnasium at Town Hall is not air conditioned and the room has gotten hot, particularly Tuesday, despite the use of fans.

Duplin said the town currently has 11,969 voters eligible to participate in the Sept. 6 State Primary.

DEMOCRATIC PRIMARY

The Democratic primary features five contested races. While Attorney General Maura Healey is technically running against State Sen. Sonia Chang-Díaz to serve as the Democratic nominee for governor, Chang-Díaz withdrew from the race in June.

Salem Mayor Kimberly Driscoll, State Rep. Tami Gouveia and State Sen. Eric Lesser are the Democratic candidates running for lieutenant governor.

Former Boston City Councilor Andrea Campbell, labor attorney Shannon Liss-Riordan, and 2018 lieutenant governor candidate Quentin Palfrey are running for the Democratic nomination for attorney general. But Palfrey withdrew from the race at press time and is now endorsing Campbell.

The two candidates running for the Democratic nomination for secretary of state are incumbent William Galvin and NAACP Boston Branch President and Civil Rights attorney Tanisha Sullivan.

State Sen. Diana DiZigolio (D-Methuen) and former state Transportation Secretary Christopher Dempsey are the two Democratic candidates running for state auditor. This is an open seat as Auditor Suzanne Bump decided not to run for re-election.

The candidates running unopposed in the Democratic primary are: Congressman Seth Moulton, State Treasurer Deborah Goldberg, Governor’s Councillor Eileen Duff, District Attorney Marian T. Ryan and Sheriff Peter J. Koutoujian.

There are no candidates running for Democratic nomination for either the Massachusetts House of Representatives or State Senate.

REPUBLICAN PRIMARY

The Republican primary features two contested races. Former State Rep. Geoff Diehl and Wrentham businessman Chris Doughty are running for the Republican nomination for governor, and are looking to succeed outgoing Republican Gov. Charlie Baker who opted not to run for a third term. Former President Donald J. Trump has endorsed Diehl but House Minority Leader Bradley H. Jones Jr. (R-North Reading) informed the Transcript that he will be voting for Doughty in the State Primary.

“While I have not formally endorsed any Republican candidate for governor, I voted for Chris Doughty at the Republican State Convention and will be voting for him in the Sept. 6 State Primary,” said Jones.

Former State Rep. Leah Allen and former State Rep. Kate Campanale are running for the Republican nomination for lieutenant governor. The positions of governor and lieutenant governor are elected independent of each other in Massachusetts; Allen has stated that she is aligned with Diehl while Campanale is running with Doughty.

Including Rep. Jones, there are seven candidates running unopposed in the Republican primary. Incumbent State Sen. Bruce Tarr of Gloucester who is the Senate Minority Leader, Peabody businessman Robert May is running for Congress. Cape Cod attorney James R. McMahon III is running for attorney general. Nashua, New Hampshire-based WSMN radio host Rayla Campbell is looking to serve as secretary of state, Isabella Stewart Gardner Museum Security Director Anthony Amore is looking to serve as the commonwealth’s next state auditor and Michael C. Walsh of Lynnfield is seeking the fifth district seat on the Governor’s Council

There are no GOP candidates running for Middlesex County district attorney, Middlesex County sheriff or state treasurer.
