Show me the HB 2 vote by district.

HB 2, the General Appropriations Act, cleared the House 66–34 on 30 April on concurrence with the Senate's amendments; the Senate had passed it 27–23 a week earlier. The 34 no votes were 33 Republicans and one Democrat, concentrated in the east and the Bitterroot. The governor returned it with line-item vetoes on 19 June, and it became Chapter 776.

Montana became the 41st state on November 8, 1889. Its public record tells the story of the laws, decisions, people, and institutions that have shaped the state ever since.

We believe public information should be accessible to everyone, and understanding it should be just as easy. That's why we built 41.
