Extreme Maps - Laura Royden and Michael Li, Brennan Center. Executive Summary: “Using data from the 2012-2016 election cycles, Extreme Maps finds that partisan bias resulting largely from the worst gerrymandering abuses in just a few battleground states provides Republicans a durable advantage in the current Congress. These ‘extreme maps’ were all drawn in states under single-party control; the report finds that conversely, maps drawn by independent commissions, courts, or split-party state governments had significantly less partisan bias in their maps.”
