Mayor Marty Walsh on Friday restated that he won’t be getting involved in the race to replace him in the state House of Representatives, after his mother and brother appeared at one hopeful’s campaign kick-off in Fields Corner.

“I’m completely staying out of the race,” Walsh said on his way into a speech to the New England Council at the Boston Harbor Hotel.

On Thursday night, Mary Walsh and Johnny Walsh, Mayor Walsh’s mother and brother, respectively, walked into the Blarney Stone restaurant in Dorchester, where attorney Liam Curran was formally kicking off his campaign. Mrs. Walsh affixed a campaign sticker to her coat, after she and Mayor Walsh’s brother signed up to volunteer on the campaign. “They’re not like family, they are family,” the brother said.

“My mother and [Liam Curran’s mother] are friends that go back a long way,” Mayor Walsh told the Reporter, when asked about their drop-in.

His brother is close with the Curran family, Mayor Walsh added. “I am too, but I’m staying out of this race. Everyone in the race – mostly everyone in the race – was very helpful to me in my race for mayor and I wouldn’t pick a side in this race.”

The 13th Suffolk District is anchored in Dorchester, with a precinct in North Quincy. Walsh held the seat for 16 years, after winning a special election in 1997.

Asked about whether unions will be taking a side in the race to replace him, Walsh, a longtime labor leader, said, “I think they’re going to be all over the place. I’m not sure from what I’m seeing. They’re kind of jumping in different camps. So I haven’t talked to anyone about it. I’m just focused on, so far, my first 25 days as mayor.”

During his speech to the New England Council, which is headed up by his predecessor in the House, Jim Brett, Walsh gave a shout-out to Dan Hunt, who is also running for Walsh’s House seat and attended the event.

Walsh praised Hunt for his work at the State House. Hunt is a former State House aide who was working in the Department of Conservation and Recreation before leaving for the campaign.

The other candidates on the ballot include former City Council candidate John O’Toole, local activist Gene Gorman, and attorney PJ McCann. Tony Dang, a Vietnamese activist and MBTA police officer, is running a write-in campaign.

The Democratic primary is March 4. The general election is set for April 1.
