Nine states withdrew from the only cross-state voter roll accuracy system (ERIC) and now have no effective replacement, making their voter databases less accurate than before

The Electronic Registration Information Center (ERIC) is the only system that allows states to cross-reference voter registration records across state lines to identify voters who have moved, died, or are registered in multiple states. Between 2022 and 2023, nine states with Republican leadership withdrew from ERIC after it became a target of conspiracy theories: Louisiana, Alabama, Florida, Missouri, West Virginia, Iowa, Ohio, Texas, and Virginia. These states collectively represent tens of millions of registered voters whose records are now maintained without cross-state verification. The immediate consequence is that these states' voter rolls are becoming less accurate over time, not more. Alabama and Missouri took months after leaving ERIC to develop alternative plans for cleaning their voter rolls, and the plans they came up with are less rigorous than what ERIC provided. Without cross-state data sharing, a voter who moves from Texas to California may remain on the Texas rolls indefinitely, which feeds exactly the kind of "dead voters" and "double registration" narratives that motivated leaving ERIC in the first place. It is a self-fulfilling prophecy: states left a system that prevented list accuracy problems because of conspiracy theories about list accuracy problems, and now they actually have list accuracy problems. Meanwhile, the remaining ERIC member states (24 plus DC) lose the data contribution from those nine states, degrading the system's effectiveness for everyone. This problem persists because voter roll maintenance in the U.S. is decentralized by design—there is no national voter registration database, and the Constitution gives states primary authority over elections. ERIC was a voluntary workaround to this structural fragmentation, built as a nonprofit consortium. But because participation is voluntary, states can leave whenever they want, and because ERIC became politically coded, the decision to stay or leave became a partisan signal rather than a technical one. A new alternative system that some states explored had its server attacked and was temporarily brought down, illustrating how difficult it is to build reliable cross-state election infrastructure outside of established institutions.
