Interstate Voter Registration Crosscheck Program

Crosscheck was initiated in December 2005[http://www.kssos.org/forms/communication/canvassing_kansas/march06.pdf Thornburgh signs four-state agreement] at the Midwest Election Officials Conference (MEOC) by the office of the Kansas Secretary of State in coordination with Iowa, Missouri and Nebraska. The program combined each state's voter rolls into a database and sought to identify potential duplicate registrations by comparing first name, last name, and full date of birth. In 2006, the first crosscheck was conducted using voter registration records from Kansas, Iowa, Missouri, and Nebraska. In 2017, the last Crosscheck was conducted with records from 28 states.{{Cite web|url=https://drive.google.com/file/d/0B5XYKw4YT8ObNU1hVHZtYy0yUTA/view?usp=drive_open&usp=embed_facebook|title=Copy of CrossStateCheckStatistics 2017.xlsx|website=Google Docs|access-date=2019-12-14}}

The program was administered by the office of the Kansas Secretary of State[http://www.kssos.org/forms/communication/canvassing_kansas/dec13.pdf Interstate Crosscheck Program Grows] as a free service to all member states.

Under then-Kansas Secretary of State Kris Kobach, the program expanded rapidly from thirteen states in 2010 to a peak of 29 states in 2014. In 2017, Crosscheck analyzed 98 million voter registration records from 28 states and returned 7.2 million "potential duplicate registrant" records to member states.{{Cite web|url=https://drive.google.com/file/d/0B5XYKw4YT8ObNU1hVHZtYy0yUTA/view?usp=sharing&usp=embed_facebook|title=Copy of CrossStateCheckStatistics 2017.xlsx|website=Google Docs|access-date=2019-12-14}}

Crosscheck considered two voter registrations potential duplicates if they matched on first name, last name, and full date of birth{{Cite web|url=https://wei.sos.wa.gov/agency/osos/en/press_and_research/weekly/Documents/Participation%20Guide%20with%20Comments.pdf|title=Crosscheck Participation Guide|access-date=2018-02-01|archive-date=2018-12-07|archive-url=https://web.archive.org/web/20181207145620/https://wei.sos.wa.gov/agency/osos/en/press_and_research/weekly/Documents/Participation%20Guide%20with%20Comments.pdf|url-status=dead}} even if the last four digits of the social security number (SSN4) of the two records did not match, or when one or both SSN4 were missing.

Matching based on first name, last name, and date of birth "fails for practically all common American names" according to ID Analytics analysis{{Cite web|url=https://www.idanalytics.com/media/The_Trouble_With-Names_White_Paper_FINAL.pdf|title=The Trouble with Names/Dates of Birth Combinations as Identifiers}} of a database of over 300 million unique records.

Crosscheck's use of loose matching standards led to a high rate of false positives: pairs of voter registration records lacking a match on SSN4 but who are identified as "potential duplicate registrants" by Crosscheck. Although false positives created a myriad of issues, the Kansas Secretary of State's office did not publicly release the percentage of their widely publicized "potential duplicate registrants" which were false positives. Independent researchers point to public data from Virginia's 2013 Annual Report on List Maintenance, which documented a 75% false positive rate.{{Cite web |url=https://www.elections.virginia.gov/Files/maintenance-reports/2013SBEListMaintenancereport.pdf |title=Archived copy |access-date=2018-02-01 |archive-date=2018-02-02 |archive-url=https://web.archive.org/web/20180202071528/https://www.elections.virginia.gov/Files/maintenance-reports/2013SBEListMaintenancereport.pdf |url-status=dead }}

For voters and member states, misidentification can be costly. Each voter who is misidentified faces an incremental privacy risk when their personally identifying information is exported to at least one state beyond his or her state of residence, and the registrant risks being inappropriately inactivated or removed from voter rolls. In Ada County, Idaho, election officials relied on Crosscheck's list of "potential duplicate registrants" to mistakenly remove 766 voters.{{Cite news|url=http://idahonews.com/news/truth-squad/ada-county-wrongly-strips-more-than-750-voter-registrations|title=Ada County wrongly strips more than 750 voter registrations|last=Powell|first=Jacqulyn|work=KBOI|access-date=2018-02-01|language=en-US}} None were duplicate registrants.

To avoid inappropriate deletion of eligible voters as occurred in Ada County, member states invested in extensive processing to vet each Crosscheck record. In May 2018, the New Hampshire Secretary of State's office reported that 817 work hours over nearly a year were required to process the 2017 Crosscheck results for their state. Despite that intensive effort, staff found no evidence of widespread double voting.{{Cite news|url=https://www.wmur.com/article/exhaustive-investigation-reveals-little-evidence-of-possible-voter-fraud-in-nh/20955267|title=Exhaustive investigation reveals little evidence of possible voter fraud in NH|last=DiStaso|first=John|date=2018-05-30|work=WMUR|access-date=2018-11-23|language=en}} Similarly, Virginia's 2015 Annual List Maintenance Report stated "the Crosscheck program does not have a direct fee associated with it, however, the initial data received from Crosscheck requires significant agency handling to determine what data is usable and what data is not usable. Crosscheck data is prone to false positives since the initial matching is only conducted using first name, last name, and date of birth. The need to greatly refine and analyze Crosscheck data has required significant ELECT staff resources that are not accounted for when proponents claim the program is 'free'."{{Cite web|url=https://www.elections.virginia.gov/Files/maintenance-reports/2015SBEListMaintenancereport.pdf|title=Virginia Annual List Maintenance Report|access-date=2018-02-01|archive-date=2017-12-18|archive-url=https://web.archive.org/web/20171218031246/https://www.elections.virginia.gov/Files/maintenance-reports/2015SBEListMaintenancereport.pdf|url-status=dead}}

Prior to the legally mandated suspension of the program, 12 states (Alaska, Arizona, Colorado, Florida, Illinois, Kentucky, Massachusetts, New York, Oregon, Pennsylvania, Virginia, and Washington) had withdrawn from the free program.{{Cite web|url=https://www.leavecrosscheck.com/states-exit|title=States that left Crosscheck|website=Leave Crosscheck|language=en-US|access-date=2019-12-14}}

Despite over seven million "potential double registrants" being "flagged" by the Crosscheck program in 2014, less than four people were charged with voting more than once, and not a single flagging led to a conviction, casting doubt on the system's usefulness.{{cite web |title=Voter registration |url=http://voter-registration.net/ |access-date=19 February 2019}}

The loose matching standards used to identify "potential duplicate registrants" by the Kansas Secretary of State also raised significant concerns about the opportunity for racial bias in list maintenance. According to "Health of State Democracies", "50 percent of Communities of Color share a common surname, while only 30 percent of white people do," so that in the program's flagged lists, "white voters are underrepresented by 8 percent, African Americans are overrepresented by 45 percent; Hispanic voters are overrepresented by 24 percent; and Asian voters are overrepresented by 31 percent".

After examining "potential duplicate registrant" lists from some of the participating states, investigative reporter Greg Palast claimed the Crosscheck system "disproportionately threatens solid Democratic constituencies: young, black, Hispanic and Asian-American voters" with the intention of securing Republican victories. Palast concluded this was achieved by eliminating discrete individuals based on nothing more than similarity of name, a method with a "built-in racial bias" that especially eliminated voters from targeted minorities with a more limited pool of given names, for example, Hispanic voters named Jose Garcia.[https://www.rollingstone.com/politics/features/the-gops-stealth-war-against-voters-w435890 The GOP's Stealth War Against Voters] {{Webarchive|url=https://web.archive.org/web/20170903204215/http://www.rollingstone.com/politics/features/the-gops-stealth-war-against-voters-w435890 |date=2017-09-03 }}, Rolling Stone, 24 August 2016. Palast expanded on his reporting in a 2018 documentary film titled [https://www.youtube.com/watch?v=0s2x5vPx7i4 The Best Democracy Money Can Buy]

However, presence on the "potential duplicate registrant" list did not mean a voter was removed from the rolls.{{Citation needed|date=May 2022}} Independent investigators found that most states reported not using the Crosscheck "potential duplicate registrant" lists in any way.{{Citation needed|date=May 2022}}

Schwab's settlement acknowledged errors in handling voters' private data and requires that Kansas suspend the program until stringent data security standards are in place.{{Cite web|url=https://www.aclukansas.org/en/press-releases/aclu-kansas-settlement-puts-crosscheck-out-commission-foreseeable-future-program|title = ACLU of Kansas settlement puts "Crosscheck" out of commission for foreseeable future; program suspended until safeguards added|date = 10 December 2019}}

Crosscheck was frequently cited{{by whom|date=October 2020}}, without supporting evidence, as a critical tool to prevent voter fraud. Critics{{who|date=October 2020}} said that Crosscheck's utility was limited to a very specific type of fraud (double voting), in a very specific situation (across state lines), at very specific times (general elections only).{{citation needed|date=October 2020}} Double voting within a state cannot be detected. Double voting in a primary election cannot be detected.{{citation needed|date=October 2020}} Voting on the records of a deceased person cannot be detected.{{citation needed|date=October 2020}}

In addition to problems with false positives and limited scope, Crosscheck has also had false negative results: the failure to recognize voters who are registered in two states if there is even a slight variation in their name. For example, Vic Miller registered in Kansas would not be recognized as the same as Victor Miller registered in Missouri despite the same full date of birth and last four digits of the social security number.{{citation needed|date=October 2020}}

Debate about Crosscheck is part of a larger, ongoing controversy over whether or not such voter registration programs are a valid means of protecting against fraud.

A 2018 study by researchers at Stanford University, University of Pennsylvania, Yale University, and Harvard University quantified the tradeoff between voter accessibility and electoral integrity when purging a likely duplicate registration from another state using Crosscheck.{{Cite web|url=https://5harad.com/papers/1p1v.pdf|title=One Person, One Vote: Estimating the Prevalence of Double Voting in U.S. Presidential Elections|last=Goel|first=S|date=2018-11-23|website=5harad.com }} Their analysis of Crosscheck results in from Iowa in 2012 and 2014 suggests that for every double vote prevented, use of Crosscheck's proposed purge strategy impedes approximately 300 legitimate registrations. This finding is in a "best practices" scenario in which all false positives have been removed. The authors emphasize that election authorities should consider the tradeoff between election access for all eligible voters and fraud prevention.
