The latest in Arizona

Oct. 29, 2021

On Oct. 28, the Arizona Independent Redistricting Commission granted preliminary approval to a congressional map that creates five Republican-leaning seats, two Democratic-leaning seats and two highly competitive seats — bad news for multiple Democratic incumbents in the state.

Under the approved proposal, Democratic Rep. Tom O’Halleran’s 1st District — which currently has a partisan lean of R+6 — gets redrawn into the new, much redder 2nd District. It’s possible that Republican Rep. Paul Gosar, whose 4th District would be radically altered, would challenge O’Halleran under these new lines — assuming both run for reelection.

The plans also make Republican Rep. David Schweikert’s current 6th District more competitive, although not as much as previous proposals did. The plan also creates two competitive seats around Phoenix and Tucson at the expense of more Democratic-leaning seats on the current map.

Thursday’s vote is not final, however. The map now goes out for public comment, and commissioners said they expected to make tweaks to the map in December.
