Ridding Your State of Crosscheck


The Interstate Crosscheck System, known as Crosscheck, is a program some states have been using to “clean up” their rolls of registered voters. The problem is, Crosscheck has proven to be wildly inaccurate and so voters who should still be registered get kicked off. Eight states have already exited the program.

The Washington Post wrote about a statistical analysis that was done on the Crosscheck system and found that for every one voter that should be taken off the voter rolls, it found 200 false positives. That’s a 99%+ error rate.

One example from the article: In 2004, there were 282 William Smiths who were registered to vote in New Jersey. Statistically, you’d expect at least four of them to share the same birthday. Using Crosscheck’s system, all four of them would be flagged as potentially fraudulent voters.

Every state has a need to clean up their voter rolls from time to time, but Crosscheck is suppressing far more voters than it is helping states. There are other systems that are much better.

First, check this map to see if your state is using Crosscheck.


Next, if your state is still using Crosscheck, it is time to write to your state legislators and ask them to exit Crosscheck. 

You can get the email addresses of your state legislators here.

Jennifer Hofmann has a terrific script from her weekly Action Checklist for Americans of Conscience that you can use as the basis for your letter/email:

Script: Dear [name], I am a resident of [town] and am writing to request that [State] become the 9th state to exit the Interstate Crosscheck System. Its history of purging legitimate voters, leaking citizens’ data–including social security numbers–and creating fraud false-positives jeopardizes an essential tenet of our democracy: the vote. Please serve your state by choosing a more secure, less-partisan option. Thank you.

Thank you for helping to rid our states of Crosscheck!
