BISMARCK, N.D. (AP) -- North Dakota stands out as the only state that doesn't require voter registration, and casting one's ballot is a quick and relatively painless process that is prized by residents for its simplicity and uniqueness.
It's a low-tech system that most election officials say works just fine, even in an era when hacking has raised concerns about the security of America's elections.
The system's boosters say it's no more vulnerable to fraud or abuse than states that require registration.
But the state has been growing in recent years, as the oil fracking boom has attracted workers from all over the country.
That concerns Kevin Glatt, the Burleigh County auditor in Bismarck. He worries whether the system can keep working as the state grows.
