This article from Nate Silver's 538 is very interesting, and bucks the MSM narrative about gerrymandering - one that concludes gerrymandering radically and unambiguously favors Republicans. What is clear is that gerrymandering is not a one-sided exercise. But what is surprising is that Democrats - who complain incessently about gerrymandering - seem to be rather good at it. As the article explains, "Democrats have picked up more seats than Republicans....so far."
