The Geeks Who Put a Stop to Pennsylvania’s Partisan Gerrymandering

The playbook is simple: Concentrate as many of your opponents’ votes into a handful of districts as you can, a tactic known as “packing.” Then spread the remainder of those votes thinly across a whole lot of districts, known as “cracking.” If it works as intended, the opposition will win a few districts by a landslide, but never have enough votes in the rest to win the majority of seats. The age of computer-generated data splicing has made this strategy easier than ever.

Until recently, courts have only moved to stop gerrymandering based on race. But now, the law is taking a closer look at partisan gerrymandering, too.
