Gerrymandering comes to the forefront. See www.princeton.edu for a video about standards for extreme partisan gerrymandering that we are advocating, based on simple concepts of partisan symmetry and basic statistics. The explainer is pretty spiffy!

Want to know how gerrymandering has gotten so bad in the last few decades? Here’s a history (with numbers) in The American Prospect. A sidebar explains the math.

Finally, we have an interactive website for you to explore the offenses: gerrymander.princeton.edu. It documents Congressional and state-legislature gerrymanders, including Wisconsin Assembly, the topic of next week’s oral arguments before the Supreme Court in Gill v. Whitford.

We hope you enjoy these explorations!
