The latest in Idaho

Feb. 15, 2022

On Feb. 11, Idaho’s Supreme Court unanimously upheld the state’s new congressional map, rejecting a challenge from an Idaho resident who argued that the map violated Idaho law. This means that the map approved by Idaho’s bipartisan redistricting commission back in November has likely cleared its last legal hurdle.

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 Ada County 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.
