With such measurement instability, I don’t think the Efficiency Gap measurement can be considered a reliable indicator of the extent of partisan gerrymandering of Arizona election districts.

If the just completed legislative session were a school year, the Class of 2018 would not be making the Honor Roll.

A raft of changes is coming to a Republican-led effort to overhaul the Arizona commission responsible for redrawing the state’s congressional and legislative district boundaries.

Secretary of State Michele Reagan has joined with Republican interests in asking the U.S. Supreme Court to void the state’s current legislative redistricting plan.

The Arizona Independent Redistricting Commission will once again take on a big-name Washington, D.C., attorney to argue its case before the U.S. Supreme Court.

The U.S. Supreme Court’s ruling that upheld the Arizona Independent Redistricting Commission’s right to draw congressional boundaries opened the door for a second, long-dormant challenge to the districts to move forward.

The U.S. Supreme Court will decide whether the lines for the state’s 30 legislative districts were illegally drawn.

The U.S. Supreme Court ruled upheld the Arizona Independent Redistricting Commission’s authority to draw congressional districts, defying expectations that it would return that power to the Legislature for the first time in more than 20 years.

If the U.S. Supreme Court returns authority for congressional redistricting to the Legislature, lawmakers will have to become familiar again with a process they haven’t used in nearly a quarter century.

Even if the US Supreme Court rules that the IRC lacks the authority to draw congressional districts, Dems may have a chance to hold on to the current congressional map for at least one more cycle.
