Metsker said that each one of the 196 voting locations has a USB drive with voter data. The drives normally take seconds to upload, but Tuesday night each drive was taking more than a minute to upload, leading to long delays.
JoCo election commission:
1 encrypted USB drive for each of the 196 voting locations.
Each one should take seconds to upload.
Tonight, they are taking around one minute (or more). Multiple that by 196 and you get a LONG delay pic.twitter.com/vu6xfpLXM4
The Johnson County Election Office released a statement Wednesday saying it was working with the vendor to figure out what caused the delay, how to resolve the issue and make sure it doesn't happen again.
