CONCORD — New Hampshire will soon be comparing its voter checklists with registration rolls in 29 other states, in the hope of avoiding duplicate registrations that lead to duplicate voting.
The Interstate Voter Registration Crosscheck Program, which started in Kansas, has been steadily enlisting other states since 2006, when four Midwestern states began to share voter data.
Proponents of the checklist say it’s an important tool in preventing voter fraud, and will become more effective as more states join. Critics say the process is flawed and results in many false duplicates, mostly involving minority and younger voters.
New Hampshire lawmakers passed a bill earlier this year that authorizes the secretary of state to participate. His office is now compiling data from the November election for submission to the database.
