Crosscheck undermines privacy, right to vote and vote integrity. 


Note: While all of the below is still correct, we were successfully able to HALT Crosscheck so that it did not run in 2018. After a collaboration with Indivisible Illinois, the data security risks were exposed nationally. States balked about sending their data. Kobach vowed to fix the issue but never delivered. 2019 status for Crosscheck is unknown.

Crosscheck is database software designed to compare voter records from member states and identify Americans who voted twice in a given election.  

While that sounds laudable, Crosscheck has two fatal flaws.  First, there are massive security risks created by Kansas' management the database of approximately 100 million voter registrations.  

Second, a fatal flaw in its data matching when processing the database places millions of validly registered American voters on a list of "Potential Double Registrants" - without justification - every year.  

Why does this matter?  

Every year, these millions of eligible and validly registered American voters are now part of a process which

  • will decide whether they stay on the voter rolls

  • releases their social security numbers and private voter data shared with at least one state besides their state of residence

Compounding these errors, Kansas is irresponsible the way the Crosscheck results are disseminated and interpreted.  Many commentators and elected officials misrepresent the  Crosscheck data- inflated by millions of wrongly accused voters  - as evidence of widespread double registrations and double voting.  

This "free" program comes at a great cost to voter rights and vote integrity, and a grave risk to the financial stability of the state totally responsible for its failures, Kansas.
