The latest in Idaho

Nov. 12, 2021

On Nov. 10, Idaho’s bipartisan redistricting commission voted a second time to approve its new congressional map. According to a commission staffer, the map officially became law when it was filed to the secretary of state on Nov. 12.

Idaho is one of the fastest-growing states in the nation, but it didn’t gain a congressional seat during reapportionment, so a lot of the debate over what the new map should look like centered around whether to split populous Ada County, where the state capital of Boise is located, between the state’s two congressional districts, as previous maps have done.

With this map, the commissioners opted to preserve the status quo. The dividing line between the state’s two congressional districts shifted slightly west to reflect population shifts, but the contours of the two districts remained largely the same, with Ada County split between them. Two of the Democratic commissioners voted against the plan, in part because of that decision.

While the shape of the districts was up for debate, the partisan outcome was not — both of Idaho’s congressional seats are safely held by Republicans, and that won’t change with the new map.
