I think just the fact that the vote watchers are there will keep many dead people in their graves.
I hate to say it but.....
While I was at the pole the worker tearing off the ballott sheet was ripping about 10% of the ballots. She couldn't get them off the tablet. Also people were returning ballots that they had mis-marked (spoiled) and were getting hew ones.
I'll say that there will be big problems by this afternoon in most places when they run out of ballots.
