What Redistricting Looks Like In Every State

The latest in Arizona

Oct. 13, 2021

On Oct. 13, the Arizona Independent Redistricting Commission released three more drafts for how its congressional districts could look for the next decade. Much like the initial preliminary plan proposed last week, the newest proposals include major shake-ups for many incumbents’ home districts. But, in a marked difference from the last map, two of the three latest proposals do restore some of the state’s majority-Hispanic districts.

Plans 3 and 4, if adopted, each create two majority-Hispanic districts, while Plan 2 creates one majority and one plurality Hispanic seat. The initial plan had one plurality Hispanic seat, but none with a majority.

Much like the initial preliminary plan, though, the new maps spell trouble for Rep. Tom O’Halleran, who might be the Democratic incumbent at the greatest risk of losing his seat under the new maps. The 1st District he currently represents has a partisan lean of R+6, and his seat (the new 2nd District) gets even redder under all three latest proposals. Plus, it’s also still possible Republican Rep. Paul Gosar, whose 4th District would be radically altered, will challenge O’Halleran under these new lines — assuming both run for reelection.

On the Republican side, Rep. David Schweikert might be the incumbent in the most trouble. Similar to O’Halleran, most of Schweikert’s current 6th District would be redrawn, and his seat (the new 1st District) would go from being Republican-leaning to competitive under all three proposals.

While Plans 3 and 4 appear to prioritize having more competitive seats, that could come at the expense of Democrats, as they currently hold two of the three swing seats in those plans. The second plan, meanwhile, has two competitive seats — one held by each party.
