The Regier family, once known for their conservative values and opposition to higher taxes and increased government spending, have undergone a dramatic political transformation. Two members of the family, Matt and Keith Regier, have recently written letters attacking a local journalist and supporting a liberal candidate for the state legislature, 'Tax-Hike' Trish Schreiber, who is backed by the Regiers' mother-in-law. The article paints the Regiers as having abandoned their previous principles in order to support Schreiber's campaign, which includes pushing for higher property taxes and a new state sales tax.
Why it matters
The Regier family's shift from conservative to liberal politics is seen as a betrayal by the author, who portrays them as selling out Montanans in order to please a wealthy California woman. This political realignment within a prominent local family is noteworthy and raises questions about the motivations behind their change in stance on key issues like taxes and government spending.
The details
According to the article, Matt Regier, a member of the Regier family, fought against property tax relief legislation during the 2025 session and has now filed a lawsuit to reverse the property tax cuts that Montanans received. His father, Keith Regier, has also joined in attacking a local journalist who is critical of their support for 'Tax-Hike' Trish Schreiber's campaign for the state legislature. The Regiers are accused of pushing for increased government spending, including a $160 million legislative office in Helena, while hypocritically claiming the state budget is too high.

- Keith Regier recently wrote a letter to the editor attacking the local journalist.
- Matt Regier's political action committee received $60,000 from Rita Schreiber, the mother-in-law of 'Tax-Hike' Trish Schreiber.
