The U.S. Supreme Court this week is hearing arguments in a challenge to Maryland's congressional map, which is often held up as a textbook example of partisan gerrymandering.

For a sense of the extent of the Democrat-drawn gerrymander, consider this: In 2016, Republican candidates won 37 percent of the statewide two-party vote for U.S. House seats. But because of the way Democrats drew district boundaries after the 2010 Census, that translated to just one of the state's eight House seats.
