Incumbents won every contested race on Newton ballots in the Tuesday, Sept. 1 primary, with state Rep. John Lawn, U.S. Rep. Jake Auchincloss and U.S. Sen. Ed Markey all advancing to the Tuesday, Nov. 3 general election.

Lawn defeated Newton City Councilor Alison Leary 61% to 39% among Newton voters in the Democratic primary for the 10th Middlesex District, according to Fig City News. The district also includes parts of Waltham and Watertown. Lawn will run unopposed in November.

"It's an honor," Lawn told Fig City News on election night.

The race was a rematch of their 2020 primary, when Leary came within six points. This time, Lawn's margin in Newton grew to 22 points. Lawn, who chairs the Joint Committee on Health Care Financing, outraised Leary more than four to one: $180,101 from 580 donors this cycle, compared with Leary's $40,558 from 165 donors, according to a Fig City News analysis. Leary contributed $13,500 of her total herself. Gov. Maura Healey had endorsed Lawn in August.

In the 4th Congressional District, Auchincloss of Newton won 74% of the Newton vote against challenger Jason Poulos, according to the Associated Press. Auchincloss, seeking a fourth term, will face Republican Thomas Stalcup in November. He raised $3.54 million this cycle and held $7.41 million in cash as of June 30.

Markey won the Democratic U.S. Senate primary over U.S. Rep. Seth Moulton, taking 57% in Newton. Moulton had framed the race as a generational-change contest. Markey, 80, countered with a repeated refrain on the campaign trail: "It's not your age, it's the age of your ideas," according to the Telegram. Markey will face Republican John Deaton in November.

Two other incumbents also prevailed in Newton. Governor's Councilor Mara Dolan won 71% of the Newton vote in the Third District, and Middlesex District Attorney Marian Ryan, who has held the post since 2013, won 72%.

On the Republican side, Michael Minogue was projected to defeat Brian Shortsleeve for the gubernatorial nomination, winning 66% of Newton's Republican vote. Minogue received fewer than one-tenth as many Newton votes as incumbent Gov. Healey, his November opponent.

Unofficial results show 18,597 of Newton's 61,596 registered voters cast ballots, a turnout of about 30%. All results remain unofficial until certified by the Election Commission.
