The fact that hundreds of votes were missing or uncounted in mayoral balloting due to the breakdown of the electronic voting system.

"A novel electronic voting system was deployed the day of the convention. It malfunctioned, leading to doubts over whether all votes were being recorded.

Bear with me as I walk through the flaws in the delegate math: There were 800 available delegate seats at Saturday’s convention, but only 579 votes were recorded on the first ballot. Typically, nearly every delegate votes on every ballot.

Unfortunately, no one knows for certain how many of those 800 delegates were present, and the credentials report contained obvious mathematical errors and impossible figures. But the organizers did report a “ballot pool” prior to the first vote — the number of delegates and alternates combined. It was 1,031. This implies that if almost every delegate voted as per usual, there were about 580 delegates, 450 alternates, and 220 empty delegate seats. This arrangement is mathematically implausible — there were clearly plenty of alternates to fill those 220 empty seats.

The more likely scenario is that the number of seated delegates and upgraded alternates was somewhere closer to 750 or 780, and several hundred votes were lost in transmission.

The voting system was supposed to provide a confirmation of votes received, but hundreds of attendees reported receiving none. (I only received a confirmation after four attempts to vote.)"
