Democratic Partisan Gerrymanders, 1972-present

August 23rd, 2017, 12:39am by Sam Wang

The Princeton Gerrymandering Project makes it easy to browse all gerrymandering offenses for a given year. We are now starting to cross-reference these offenses with who had control over the redistricting process. It’s a daunting task, but our statistical analyst Brian Remlinger is on the case. Brian has found something interesting: from 1972 until now, [...]

As I have analyzed (see page 1296), the California Redistricting Commission has done a good job of creating competitive races where none existed before. A commission-based approach has the advantage [...]
