Or have they been hacked already?
In light of Russia's recent attacks on our electoral system, I'm surprised that this isn't getting more attention:
The State Board of Elections (SBE) fell victim to a cyberattack that was detected on July 12, 2016. Specifically, the target was the IVRS database. Once discovered, State Board of Elections closed the point of entry. On July 13th, once the severity of the attack was realized, as a precautionary measure, the entire IVRS system was shut down, including online voter registration.

The real question is whether other states would even know if they'd been compromised.
