Arizona redistricting goes to Supreme Court

[hopper]

Remember: Gerrymandering's only frowned upon when Democrats do it.

No other Democrats on this board(not sure if you did)cried when the GOP did it in 2011.

Arizona has done some weird things like SB 1070, the denial for a bakery to refuse to make a wedding cake  for a same-sex marriage couple and now this. Even Utah, Idaho, and Wyoming aren't this crazy but they are more Republican than Arizona is.

What's the legal justification for striking down commissions?

A hyperliteral reading of Article I Section 4 so that only a State legislature may devise district maps for the House of Representatives.

But that ignores that State legislatures can delegate the drawing of Congressional districts to non-partisan commissions. What they cannot do is to draft districts that grossly disenfranchise large segments of the population. Michigan is a prime example: if you live more than ten miles west of US 23 or to the north of Bay City and you are a Democrat, your voice is unlikely to be heard in the House of Representatives. The Koch syndicate owns your Representative and pulls the strings.   

Michigan is not heavily gerrymandered. Most of the Democratic areas are in and around Detroit. There are Democrats in Southwest MI but its still culturally conservative I would think thus  that area of MI elects Republicans to Congress.
