Butler County's mail-in votes will remain half-counted until Nov. 4 due to "mechanical problems" with the high-speed scanner used to process the mailed ballots.

Mail-in ballots were subject to the same scanning problems as in-person precincts. Tina Fedko, county elections spokeswoman, said the county's faster ballot scanning machine was intermittently not working throughout the day, and finally gave out in the late hours Tuesday.

“Now, the scanner has mechanical issues. I doubt that we'll get to 80% (of mail-in ballots counted), because we're down to one smaller scanner that we're using,” she said. “It's not high-speed like the other one that's been having mechanical issues.”

While roughly half of the more than 31,000 ballots the county has currently received have been tabulated thus far, Fedko estimated that the final count would not be complete until Wednesday evening, after a replacement for the higher-speed scanner was available.
