What You Need to Know About Tuesday's State Primary Election

Voters head to the polls on Tuesday for the State Primary.

Polls are open from 7 a.m. to 8 p.m. at Reading Memorial High School. See an Election Day Parking Map here.

The most closely watched race is the Democratic Congressional primary that pits incumbent John Tierney against four challengers. Recent polls show Seth Moulton running neck and neck with the incumbent.

Tierney was able to ward off a tough challenge by former State Senate Minority Leader Richard Tisei two years ago. Tisei is running unopposed in the Republican primary. Voters will decide on Tuesday who Tisei will take on in November.

Other races of note are:

Governor

The Democrats have three candidates. Attorney General Martha Coakley is the frontrunner with Steven Grossman and Donald Berwick hoping to pull off an upset.

The Republican side sees Charles Baker, who ran for governor four years ago, and Mark Fisher.

Attorney General

Maura Healey and Warren Tolman are locked in a race on the Democratic side. The winner will take on John Miller, who is the sole candidate on the Republican side.

District Attorney

Middlesex District Attorney Marian Ryan is in a tough race against MIchael Sullivan. There are no Republicans running for DA, which means the winner of the Democratic primary will be the district attorney unless there is a massive write-in campaign in November.

There are also races for lieutenant governor and treasurer.
