Louis B. Lausier was born in Biddeford, Maine, and pursued higher education in Quebec and under a prominent Maine jurist. He passed the Maine bar in 1906 and subsequently held various political roles, including serving in the Maine House of Representatives and as mayor of Biddeford for an extended period. Lausier exhibited fiscal conservatism during his tenure as mayor, notably refusing to allow the city to incur debt. His political career included participation in the Democratic National Convention and a bid for Governor of Maine, although he was unsuccessful in that endeavor.

Louis B. Lausier's political identity is marked by a distinctive blend of fiscal conservatism and progressive social concerns. His tenure as mayor of Biddeford saw a staunch refusal to allow the city to incur debt, showcasing a deeply rooted fiscal conservatism. However, Lausier's approach to education reveals a more progressive stance, as he acknowledged and sought to address the shortcomings of public schools, particularly for non Franco-American communities. This juxtaposition of fiscal restraint with a commitment to improving public services presents an intriguing conceptual tension in Lausier's political philosophy.
