The Supremes are reviewing the anti-gerrymandering case, and the thought crossed my mind that someone, particularly of the Democratic vein, should have done some research. Recall the thesis presented here, and subsequently repeated by some of the mainstream pundits (without crediting your humble servant, of course), that there aren't Red states and Blue states. There are Blue cities and Red shitkicker empty counties.
Given gerrymandering, Rightwing success in minority rule, and the actual distribution of Reds and Blues, one would expect that Red legislatures (which predominate in having re-districting power) would attack cities by pie-wedging their area so that it often/always ends up that districts have some Blue city folks outnumbered by Red shitkickers. Kind of like a spider's web. One might expect this would be easy to demonstrate with the funds, folks and time that major think tanks have. Dontcha think?
I did, and here's what I found.
Here's a Washington Post article, which references the latest Brennan Center report. Neither, that I could find explicitly calls out urban cracking.
For example, a Republican-held district near Philadelphia that had been trending toward Democrats was stretched westward to take in more conservative voters. And Democratic-leaning voters in Scranton and Wilkes-Barre were shifted out of a Republican-held seat into a Democratic-led district to help protect the GOP incumbent.
Law Street, at least, makes the case that such a process exists, but doesn't show such a district map. Oh well:
An example of cracking is when poor, urban voters are spread across districts where a large majority of the voters are rural. This prevents the urban voters from carrying much weight during elections. This is the most common type of gerrymandering.
OK, so ThinkProgress has some of the Wisconsin map. Very pretty.
[W]here Democrats lived near large blocs of Republicans, Democratic communities were "cracked" up and placed in multiple districts that were overwhelmingly likely to elect a Republican.
AKA, cities chopped up and bundled into shitkicker empty spaces.
