November 17, 2016 - It's a common question - if there's fewer ballots why can't you estimate exactly what is left? Simple answer - there's less data to rely on as the number of ballots narrow. Here's how it works:

When there are large numbers of ballots, we can rely on data extracts from signature verifications, Election Day e-ballots issued, electronic provisional ballot access codes issued, etc. However, once that volume has reduced we end up with the "problem" ballots, which cannot be tracked using the data listed above. For instance, ballots that were returned damaged (marks over barcodes, torn, liquid stains, wrinkled, etc. - yes we see it all) must be duplicated for scanning. Or, paper ballots cast at polling places that have no data tracking, which means you can't detect where they were cast. These are just a few examples of multiple stations throughout our operations that contain these ballots - and each of these ballots are treated with respect and processed with careful attention.

Of course this can be tough in close contests as it can come down to a handful of ballots - but every ballot and every vote must be meticulously accounted for - one-at-a-time.
