Last week, the Justice Department filed twin lawsuits against Maine and Oregon, arguing that the states violated federal election laws and the Civil Rights Act by refusing to give the agency full access to the states' voter data. Since May, the Justice Department has sent letters to at least 32 states requesting access to their voter registration databases, according to the Brennan Center for Justice. In the U.S., elections—and the voter data that underpin them—are managed primarily by state and local governments, not federal agencies. If the Justice Department prevails, more states may be forced to share complete voter data—including sensitive identifiers—to federal agencies, giving the government even more access to citizens' private information. If the courts side with Oregon and Maine, it may affirm states' ability to limit access in defense of voter privacy.
