An hour or so ago, a great diary analyzing the NC Redistricting and it ramifications was posted at Daily Kos. I won't attempt to copy any of it here; simply follow the link and check it out for yourself. This is the most exhaustive treatment of this topic I've seen yet, heavy with numerical facts, with a bit of reasoned analytical opinion added. Very enlightening.
A word of advice: if you click the link, make sure you have a few hours of free time ahead of you! There's more information there than can be assimilated in just a cursory look, and the information is addictive if you're a cartographic and dataset junkie like I am.
The bottom line is that after studying that diary for a while, I was a little less depressed by the 2012 electoral prospects for our state...but just a little. We've got a huge battle ahead of us in North Carolina.
