NYT: The Great Gerrymander of 2012 http://mobile.nytimes.com/2013/02/03/opinion/sunday/the-great-gerrymander-of-2012.xml

Confounding conventional wisdom, partisan redistricting is not symmetrical between the political parties. By my seat-discrepancy criterion, 10 states are out of whack: the five I have mentioned, plus Virginia, Ohio, Florida, Illinois and Texas. Arizona was redistricted by an independent commission, Texas was a combination of Republican and federal court efforts,and Illinois was controlled by Democrats. Republicans designed the other seven maps. Both sides may do it, but one side does it more often. Surprisingly absent from the guilty list is California, where 62 percent of the two-party vote went to Democrats and the average mock delegation of 38 Democrats and 15 Republicans exactly matched the newly elected delegation. Notably, California voters took redistricting out of legislators’ hands by creating the California Citizens Redistricting Commission.

A LOT (Capitalized for emphasis) of lazy thinkers go woth the “both sides are the same” b.s. so often it has become a mantra….to be exploited.
