Fifteen years ago, Arizona voters passed a ballot measure creating an independent, bipartisan commission to draw congressional districts. Over the next several years, 10 other states passed similar laws to prevent gerrymandering by state legislatures. But in 2012, Arizona Republicans sued, saying the independent commission was unconstitutional. On Monday, the Supreme Court ruled that Arizona’s commission was lawful. Supporters of the decision say it’s a victory for direct democracy. But critics say it doesn’t change current law and won’t address partisan gridlock. We discuss the Supreme Court decision and what it could mean for election reform efforts nationwide.
