What Redistricting Looks Like In Every State

An updating tracker of proposed congressional maps — and whether they might benefit Democrats or Republicans in the 2022 midterms and beyond.

Who controls redistricting in Idaho in 2021?

The latest in Idaho

Sept. 15, 2021

Idaho’s nonpartisan redistricting commission released two draft congressional maps on Sept. 14, which will be presented at public hearings throughout the state in the coming weeks. One map makes a relatively simple change: It moves the dividing line between the state’s two congressional districts west to reflect population shifts, but keeps the contours of those districts largely the same. The other map, however, redraws the district lines more substantively — rather than cutting through the state capital, Boise, it creates a new, more compact district in the southwestern part of the state, and puts all of northern and eastern Idaho in the other district. Each proposal would have different implications for the way the state’s representation shakes out, but neither is likely to shift the partisan makeup of the state’s congressional delegation overall. Both of Idaho’s congressional seats are safely held by Republicans, and both proposed maps would preserve that status quo.
