Who draws the districts?

On Monday the Supremes heard a case about Gerrymandering. In 2000 Arizona voters turned redistricting over to a separate commission, taking it out of the hands of the legislature. In 2012 the new map appears to favor Democrats. There was an attempt to impeach the chair of the commission, but the state Supremes prevented it. So the GOP is suing to have the law that created the commission overturned. Their reason is this phrase from the Constitution: "The times, places and manner of holding elections for Senators and Representatives, shall be prescribed in each state by the Legislature thereof." The GOP contends that means redistricting must be done by the legislature. And that implies the Constitution permits Gerrymandering.

The vote is likely to come down to Anthony Kennedy – and from his questions in oral arguments it isn't easy to tell which side of the debate he is on. The ruling will likely come in June.
