WATCH: Primary season for the 2018 midterm elections is finally upon us — and it’s not without anxiety about fairness in our election maps. Next week in Pennsylvania, voters will cast ballots in newly drawn districts after the state Supreme Court found the original Republican-drawn map unconstitutionally partisan. Meanwhile, the U.S. Supreme Court is sitting on two similar cases about partisan gerrymandering — one about a Republican-drawn map in Wisconsin and another about a Democrat-drawn map in Maryland.

Given all the courtroom drama, it’s easy to think that gerrymandering is inherently wrong. But that’s oversimplifying the issue. Although easily abused, gerrymandering can actually be a tool for good. Don’t believe it? Watch the video.
