Fort Bend County voters will head to the polls Tuesday, Nov. 3, with new safeguards in place after a file-upload error knocked out voter check-in at every polling site during the May 26 primary runoff.

Elections Administrator Chase Wilson said in emails to Houston media outlets over the summer that the county's vendor installed a safeguard to prevent an incorrect file from being loaded into the poll book system. The county also now requires multi-level verification from senior administrators before any poll book information is updated.

The changes follow what Wilson called a human error during the May runoff. An elections employee uploaded the wrong file to the electronic voter check-in system, ABC13 first reported. Records obtained by ABC13 showed it took three hours to fix the problem. Some voters had to cast provisional ballots, and others saw machines reject their identification.

"This issue is just entirely has to do with the check-in process at the polling locations, resulting in delays in today's vote," Wilson said at a May press conference, according to KHOU 11. Officials at the time said the error did not affect the accuracy of ballots cast.

Wilson wrote in a follow-up email to KHOU 11 that the office trained staff "3 levels down internally on the process but have restricted anyone from performing the step without senior administration approval and oversight."

The accounts differ on what happened to the employee who uploaded the wrong file. Wilson told ABC13 the county took action through "a combination of workflow reassignment and restructuring." Officials told KHOU 11 the employee "is no longer with the elections office."

Wilson also told ABC13 he hopes Tuesday's election may be the last using the current system. He said he hopes to have a new voter registration system running by May. The administrator said the change would not be something voters notice.

Wilson did not respond to ABC13's questions on Monday, Nov. 2, the station reported. He had not done an on-camera interview with ABC13 since the May press conference. KHOU 11 reported that its reporter tried for weeks to get Wilson to agree to an on-camera interview.

Fort Bend County residents interviewed by the two stations expressed mixed confidence. Twila Lewis, who planned to vote Tuesday, told ABC13, "Please get it right. Let's get it right this year so we can all get our votes in, and everyone will count."

Voter Ese Ogbebor told ABC13, "I would hope they have corrected the problem. I can't imagine how frustrating that would be."

Election officials told KHOU 11 that if technical issues affect the check-in process Tuesday, voters will be offered provisional ballots, as they were during the May runoff.
