Westchester voting snafu stemmed from a change in one Ardsley contest

2:38pm: "[County Executive Ken] Jenkins said the initial suspicion that it was due to the thickness of the paper turned out not to be the case. Rather it involved bar codes on the ballots that did not match what the machines were expecting."

8:58pm: "[In Ardsley] the incumbent village justice, David Rifas, was not formally nominated for re-election to a new four-year term. But the initial ballots omitted the race entirely... When the Westchester County Board of Elections realized the problem, the ballot definition file that lists the races was updated. That file was used to print the ballots, but the scanners were still programmed with the old file. Only in Ardsley did the scanners manage to read the ballot sheets."

10:15pm: "Even though the problem stemmed from just a change in the village justice election in Ardsley, it required an update to the countywide election programming. When the identifying codes the scanner uses to read the ballots changed for Ardsley’s race they changed as well for all the other races. But because the scanners were using the original programming, they rejected the updated ballots because they did not recognize the identifying codes."
