I just got off the phone with officials in Adams County. They told me that they've identified the source of the computer problems.
When some voters went to check their voter eligibility at the polling precincts they were told they were not eligible to vote. Officials think that that was because poll workers were putting too much personal information into the system. Believe it or not, I'm told the system works better when you put less information in.
Here's an example. If you put someone's first name, last name, address, city, state and ZIP Code and any part of that information isn't exactly correct then the computer rejects it.
Officials think they have corrected the problem by instructing all of the polling precincts in Adams County to only use someone's first name, last name and date of birth.
If someone was rejected previously they were still allowed to vote using a provisional ballot.
