Rep. Michael Soter, a Bellingham Republican, says he has narrowed his focus to potentially running for a statewide constitutional office in 2026, telling the Herald he has multiple donors lined up if he decides to jump into the mix.

The fourth-term state representative has been mulling a campaign for higher office this year, and previously told the Herald he was not ruling out challenging U.S. Sen. Ed Markey. But in a statement Tuesday, Soter said he is now considering a “statewide constitutional office.”

“We are still on a timeline for summer to make a final decision,” Soter said. “Multiple donors and supporters are in if we decide to run for a statewide constitutional office. They feel very positive of what we are seeing on our opportunities as a potential statewide candidate.”

Massachusetts’ constitutional officers include the governor, lieutenant governor, secretary of the commonwealth, attorney general, treasurer, state auditor, and members of the Governor’s Council.

The Republican field of statewide candidates for the 2026 election is still small. Most incumbent Democrats have not yet said whether they plan to run for reelection, except Gov. Maura Healey.

Mike Kennealy, the former housing and economic development secretary under Gov. Charlie Baker, launched a Republican campaign for governor earlier this month.

Brian Shortsleeve, a venture capitalist and former MBTA manager, is also considering a run and has enlisted the services of a well-known Republican strategist.

Soter traveled to Washington, D.C. in February to meet with “key people” in conservative circles, including strategists who work on statewide campaigns in Massachusetts and others involved in politics.

“If we decide to seek statewide constitutional office, it will be by the end of the summer as we are putting strategies and scenarios together,” he said in his Tuesday statement.

Soter had just under $7,000 in his campaign account as of April 2, according to state records.
