Tennessee's secretary of state says the Supreme Court ruling on Arizona's voter verification doesn't change the way we do things here:
It is our opinion that the recent Supreme Court ruling does not impact our current process in Tennessee for verifying citizenship for voters.
Arizona rejected new voter registrations that did not include proof of citizenship, such as birth certificates. Our process in Tennessee is different. We do not require that type of documentation when registering to vote. However, each registering voter must swear under penalty of perjury that he or she is a citizen.
We do have a process of verifying citizenship, but that process is only used if we have evidence a person is not a U.S. citizen and is therefore ineligible to be included on our voter rolls.
