South Hamilton’s Michael Minogue spoke with MassGOP Chair Amy Carnevale about running for governor of Massachusetts, another sign that the local mega donor to Republicans is weighing a campaign in 2026, according to multiple sources with knowledge of the discussion.

Minogue, who is still relatively unknown to Massachusetts Republican political operatives, is the latest person to envision themselves challenging Gov. Maura Healey, a first-term Democrat from Arlington who has said she plans to run for a second term next year.

The extent of Minogue’s conversation with Carnevale is unclear but the pair did discuss his interest in running for governor of the Bay State, several sources told the Herald on the condition of anonymity to discuss a previously unreported conversation.

A spokesperson for the Massachusetts Republican Party declined to comment when reached by the Herald.

Carnevale regularly fields calls from prospective candidates for elected office, including for posts ranging from local State House races to congressional contests.

Minogue, who could not immediately be reached for comment Wednesday, has a long history of donating to national conservative causes and candidates, according to federal campaign finance records. Minogue is unenrolled, according to state records verified by his address and birthday.

In just the last year, the former head of the medical technology company Abiomed donated hundreds of thousands of dollars to the Republican National Committee and a fundraising committee associated with President Donald Trump, federal filings show.

Back in Massachusetts, Minogue gave $10,000 to the Massachusetts Republican Party’s federal account and another $5,000 to its state account in February, according to state and federal records.

He also donated $1,000, or the maximum amount allowed in a calendar year, to Democratic Boston mayoral candidate Josh Kraft, state campaign finance filings show.

Minogue backed John Deaton, who ran as a Republican against Elizabeth Warren last year for U.S. Senate, with several thousands dollars.

He shuttled $1,000 to state Senate Minority Leader Bruce Tarr of Gloucester in October 2017 and a total of $2,000 to former Gov. Charlie Baker over the course of 2010, 2014, and 2016, state records show.

Massachusetts voters head to the polls to select their next governor in fall 2026, and the Republican field is becoming increasingly crowded.

Mike Kennealy, a former cabinet secretary under Baker, announced Monday that he plans to run for governor as a Republican. Massachusetts Democrats immediately attempted to link Kennealy to Trump and other National conservatives.

Brian Shortsleeve, a venture capitalist and former chief administrator of the MBTA, is also weighing a gubernatorial campaign as is state Sen. Peter Durant of Spencer.

But any Republican who jumps into the contest is set to face an uphill battle with Trump back in the White House and Democrats in control of the Massachusetts Legislature and all of the constitutional offices.

Healey does not have a declared challenger, though criminal justice advocate Andrea James filed paperwork last month to run for governor and told the Herald she was “exploring” a campaign.

Healey, the first woman and openly gay candidate elected to the Governor’s Office, said earlier this year she will seek a second term and has gone on a fundraising streak since January. She raised more than $404,000 in March alone, her best haul since the 2022 election, according to state records.

In a February radio interview, Healey said she is “really proud” of her record so far.

“I plan to run for reelection because there’s a lot more to do. I love my job. I feel incredibly privileged to be in this position, and I’d love to have the opportunity to continue to work for the great people of this state,” she said.
