Stephen McBride, 31, plans to challenge councillor Frank Baker for the District 3 council seat.

Baker has served on the Boston City Council for the last decade, but McBride said he brings a new voice for change.

"I'm running to be a new, progressive voice for District 3 and for Boston,” McBride told the Reporter on Tuesday. “I want to build back our small businesses in the wake of the pandemic, address systemic inequities within our schools, fight for climate justice, and be a fierce champion for all the people of District 3.”

McBride officially filed with the Office of Campaign and Political Finance over the weekend but has been thinking about running for a spot on the Boston City Council since the summer.

A Boston transplant by way of Pennsylvania,he is a Northeastern grad and works at HubSpot.

“I would like to be known for being someone who can be worked with,” he said.

If elected, McBride hopes to bring his tech background and data driven mindset to make substantial progress on issues like climate change, education and development.

When it comes to development, McBride said he wants to ensure that newly developed areas of the neighborhood, such as Dot Block, provide real, affordable housing options.

“We should learn from the Seaport,” McBride said.

McBride and his husband moved to Dorchester three years ago and is “running to be another proud, LGBT voice on the council” to better represent the city.

“I wouldn’t say that this is necessarily a slight against him,” McBride said of his campaign to unseat Baker, noting that “I think he’s done great things for Dorchester.”

In order to get on the ballot, McBride will have to garner 200 signatures from the district which includes Dorchester and a portion of South Boston and the South End this spring. Nomination papers are not available for another two months— on April 13.
