Redistricting Next

PG's ER posted this first... but Pittsburgh and Pennsylvania redistricting gets a mention on page 3 of this from the CQ:  The Next Battle to Draw the Lines. Touched upon by the CQ piece, but a fuller discussion of Republic over-reach following the 2000 census was discussed more fully in the Wall Street Journal a couple years ago.  How much redistricting can change the literal political landscape I have poked at in the past in:  Pennsylvania's Rorschach test.
