The latest in Montana

Nov. 12, 2021

For the first time since 1993, Montana has more than one congressional district, and on Nov. 12, the state’s bipartisan redistricting commission gave its final approval to the state’s new lines.

The map passed by the commission, which was put forward by Republicans, excludes liberal Helena from the state’s western congressional district, giving it a FiveThirtyEight partisan lean of R+10. The map was chosen over a Democratic proposal that put Helena in the western district, making it a more competitive R+7. (The eastern district is ruby-red under both maps.) In its final meeting, the commission also decided not to accept a small tweak to the map that was previously agreed to.
