Biography
Brian Miller first came to Montana to drive a bus in Glacier National Park.1 Raised in Florida, he later went to law school in his thirties and built a legal career in Helena.1 He has two adult children, and sometimes walks to his downtown office with his dog, Walter.1
Miller earned a philosophy degree at Emory University and his law degree at the University of Montana.2 He was admitted to the Montana bar in 2007 and spent three years clerking for state Supreme Court Justice Patricia Cotter.3 His practice has included consumer disputes, divorce, personal injury, employment and criminal matters, along with jury trials around the state.2
Regulating data centers has become a central campaign issue and part of his legal work.1 He represents Yellowstone County Voices, a citizens' group seeking voter approval requirements for data center projects.1 Miller argues for state and local control over those developments, citing concerns about water, surveillance and transparency.1
He faces Republican Troy Downing, independent Michael Eisenhauer and Libertarian Patrick McCracken in Montana's Second District.4 Miller supports a nonprofit model for health care and withdrawing from the conflict with Iran.4 His housing proposals include making community land trusts easier to establish and limiting rent increases for mobile home lots.1
Record and controversies
Ballot challenge withdrawn
In September 2026, Miller challenged independent Michael Eisenhauer's ballot signatures, then withdrew the case after missing a scheduling conference.5 The suit followed an inquiry into potentially fraudulent petition signatures; authorities said the questioned signatures had not been counted and they did not suspect campaign wrongdoing.5 Miller said he had mistaken the hearing time, took responsibility and cited limited time in asking to dismiss the case.5 The judge granted dismissal without prejudice; Eisenhauer defended his campaign's compliance and called the suit frivolous.5
