Vox: The research that convinced SCOTUS to take the Wisconsin gerrymandering case, explained
In June, the Supreme Court agreed to hear its first partisan gerrymandering case in more than a decade. This case, Gill v. Whitford, involves a challenge to the district plan that Wisconsin passed for its state house after the 2010 Census. The case also involves a quantitative measure of gerrymandering — the efficiency gap — that has created a bit of a buzz. One reporter compares it to a “silver-bullet democracy theorem” and a “gerrymandering miracle drug.” Another speculates that it may be the “holy grail of election law jurisprudence.”
