The Supreme Court is hearing a case on partisan gerrymandering, in which Democrats are accused of drawing districts to elect their own. The right wonders, if the left is benefiting from gerrymandering, why are they complaining so much about it?

A roundup of articles looks at the issue:

1. If Republicans rigged voting maps, why are Democrats winning so much?

From USA TODAY: "Both parties draw districts for partisan advantage, but gerrymandering only goes so far. Democrats need to remember that people aren't formulas."

2. Stop the Gerrymandering Scaremongering 

From National Journal: "Democrats are well positioned to score a historic victory in the House this year. Anti-gerrymandering activists are having a tough time coming to grips with that reality.

3. Backlash over gerrymandering decision is coming

From Philadelphia Daily News: "Since the last judicial election (2015) gave Democrats court control, look for action on long-stalled efforts to change the constitution to allow merit selection (rather than election) of state judges."
