Illinois election officials have decided the state will remain in Crosscheck, a multi-state voter registration database that critics claim is inaccurate and could lead to security breaches.

Federal election law requires states to keep accurate and up-to-date voter registration rolls. But one tool to help them do so is at the center of a partisan debate. In Illinois, many Democrats are calling on the state Board of Elections to stop participation in the Interstate Voter Registration Crosscheck Program, or Crosscheck, for short.
