CNN: “The Supreme Court has denied a request from Pennsylvania Republicans to block new congressional maps that could tilt several key races in Democrats’ favor from being used in the midterm elections.” The new map was imposed by the Pennsylvania Supreme Court after the state’s governor and legislature failed to come up with a replacement for the previous map, which the court had declared unconstitutional; see previous entry.

Meanwhile, last month Wired published a piece that looks at how experts used math and computer simulations to prove to the Pennsylvania Supreme Court that the congressional map exhibited partisan bias. It’s an interesting look at some interesting methodologies.
