Notable personal detailsOwen Zachery McCarthy is a Maine engineer and entrepreneur who ran as a Republican candidate for governor in 2026. He earned a bachelor’s degree in biological engineering from the University of Maine and an MBA from Harvard Business School. He has been involved with the University of Maine System as a trustee/board member and has worked in business roles including ventures in manufacturing/3D-printed electronics and a medical device company (MedRhythms).
The candidate supports cutting taxes and delivering tax relief for families and small businesses, reducing state spending, balancing the budget, and rolling back recent tax and fee increases while streamlining regulations to lower costs. He frames these policies as measures to restore affordability and respect for taxpayers.
The candidate’s policy plan emphasizes improving access and affordability of healthcare, expanding telemedicine, and stabilizing rural care and emergency services. The campaign frames these proposals as measures to make care more available and affordable for Mainers rather than advocating for wholesale privatization or repeal of existing programs.
Supports cracking down on illegal immigration through cooperation with federal law enforcement and reducing strain on state resources; emphasizes enforcement and border control measures rather than expansive legalization or asylum protections.
The candidate has made comments suggesting concern that Republican positions on abortion have cost elections and discussed the topic as politically consequential, but has not published a clear policy position on abortion access or specific restrictions. Public reporting about his campaign and campaign website do not provide a clear, detailed stance on abortion or reproductive-rights policy.
Supports lowering energy costs and upgrading Maine’s electric grid to attract investment and economic development, emphasizes cutting regulatory red tape and using private investment (e.g., data centers) to pay for grid upgrades, and frames energy policy primarily around affordability and reliability rather than aggressive emissions mandates. No campaign materials endorse Green New Deal–style targets or international climate agreements.
