Modeling the $5 million DHS/ICE voter data clearinghouse reported by WIRED: simulated record linkage error rates, naturalization database latency, and statutory friction under the National Voter Registration Act of 1993.
52 U.S.C. § 20507(c)(2) mandates states complete systematic voter removal programs no later than 90 days before federal elections. Federal bulk flagging during surges triggers federal court injunctions.
5 U.S.C. § 552a prohibits agencies from aggregating citizen records across disparate state databases without an approved SORN and routine-use exception published in the Federal Register.
U.S. Constitution Art. I, § 4 grants states primary responsibility over elections. Compelling state chief election officers to feed raw voter files into an ICE criminal clearinghouse faces severe federalism challenges.
DHS Systematic Alien Verification for Entitlements (SAVE) was designed for benefit eligibility case-checks, not real-time batch queries against 168M multi-sourced state records.
Secure multi-tenant data lake, API endpoints for 50 diverse state formats, encrypted storage for SSN-4, DL numbers, and home addresses.
Probabilistic entity resolution software (e.g. Senzing or Palantir modules) tuned for fuzzy name matching, transpositions, and phonetic alias clustering.
Custom enterprise service bus to bridge USCIS naturalization records, ICE ENFORCE arrest records, and Social Security death master files.
Privacy impact assessments, responding to FOIA/Privacy Act challenges, and litigating state sovereignty resistance.
