Key metric: Electoral Integrity

As a social scientist, I analyze that the Supreme Court's 2019 decision in Rucho v. Common Cause has significantly impacted electoral integrity in the United States. By ruling that federal courts cannot review partisan gerrymandering cases, the Court has effectively removed a crucial check on extreme redistricting practices. This has emboldened political parties, particularly Republicans in Texas, to engage in aggressive gerrymandering to entrench their power. The decision has sparked a partisan arms race in redistricting, potentially leading to more polarized and less competitive elections. This undermines the principle of fair representation and could erode public trust in democratic institutions. The long-term consequences may include decreased voter engagement, increased political polarization, and a weakening of the democratic process.
