As usual, those who harp on supposed Republican gerrymanders conveniently forget about Democratic gerrymanders in states like Maryland and Illinois. There is a
diary on RRH which claims that after taking Democratic gerrymanders into account, Republicans would actually gain a few seats under non-partisan maps due to self-packing. I'm not sure I believe it, but it is intellectually dishonest to ignore Maryland and Illinois, plus the Mathismander in Arizona, if you're truly concerned about partisan gerrymandering.
I'm not a proponent of eliminating partisan gerrymandering, though, as it is an American tradition as old as Elbridge Gerry.
