It's do with the unexpectedly large numbers that turned out, those that forgot to bring their registration cards and their driver's license, simply because, while you have to show a license to do any thing else, how dare you be asked to prove you are a registered voter! Not to mention those who assumed that you can vote in any precinct, as many times as you want.
Then toss in voter rolls that have not been updated due to people moving or dying....it's amazing that it only took a week to get all of the state's validated.
And people wonder why the purchases of alcohol go through the roof!!!!!!
