Immigration & Border
The candidate supports stricter enforcement and cooperation with federal immigration authorities, opposes sanctuary-state policies, and favors restricting state shelter programs for migrants while endorsing deportation of serious offenders. He frames the current situation as a migrant crisis driven by permissive state policies and calls for reforms to reduce migrant intake and increase cooperation with ICE.
Climate & Energy
Supports an all-of-the-above energy strategy prioritizing affordability and reliability, opposes what he calls costly climate mandates and surcharges, and advocates building natural gas pipeline infrastructure to lower consumer energy costs.
Public Safety & Guns
The candidate emphasizes support for lawful gun owners and responsible gun ownership while opposing new registries, broad restrictions, and measures he views as infringing on the Second Amendment. He calls for enforcing existing gun laws, faster prosecution of gun-related crimes, due-process protections in licensing, and stronger public-safety measures that back law enforcement.

AINews Summary
Last updatedJul 4, 2026
Brian Shortsleeve is still in the Massachusetts Republican governor primary and is facing Mike Minogue for the nomination after the party convention backed Minogue. He recently added $600,000 of his own money to his campaign, pushing his reported cash on hand above $1 million, and he remains behind Minogue in fundraising. Shortsleeve also named New Bedford City Councilor Shawn Oliver as his running mate. Recent polling suggests he is still little known to many voters, even as the race against Gov. Maura Healey takes shape.
