When simple rules aren’t enough

February 13th, 2018, 6:36pm by Sam Wang

As the old political-science saying goes, “all redistricting is gerrymandering.” Inevitably, choices and tradeoffs have to be made. When it comes to representation, the resulting map can end up balanced – unless partisan advantage is made the primary criterion. The Pennsylvania Supreme Court set down clear “floor criteria” for what was absolutely required in the […]

A statistical toolbox reveals Pennsylvania’s extreme Congressional plan

February 13th, 2018, 8:27am by Sam Wang

Mathematicians have been working hard to create ways to measure #Gerrymandering. 2017 was a big year on this: accumulating evidence showed PA most gerrymandered of all by two measures, among five worst by any measure.

February 5th, 2018, 11:11pm by Sam Wang

Today, U.S. Supreme Court Justice Samuel Alito denied Republican legislators’ request for a stay of the Pennsylvania Supreme Court’s redistricting decision.

Pennsylvania Congressional gerrymander overturned – and it seems likely to stick

January 22nd, 2018, 2:51pm by Sam Wang

Update, February 5th: Justice Alito denied the Pennsylvania GOP legislators’ motion for a stay. He did so without referring the matter to the full Supreme Court. Justice Alito is one of the three most conservative members of the court, and a near-guaranteed vote against restrictions on partisan gerrymandering…based on the U.S. Constitution. I would call […]

January 9th, 2018, 5:33pm by Sam Wang
