There was no evidence of large scale voter fraud, but some still say there was and have evidence of it but refuse to show it. What if the voter fraud that they were expecting to happen never happened. That is, the side that screams voter fraud actually attempted to create voter fraud that they could use against the winner and it never materialized. This could be why they are so positive that there was voter fraud because they were the ones who created it but no one could find it because it was eliminated before it could be set in motion. This would be one reason they could be sure that there was voter fraud. The reason they can't prove voter fraud might be because they would actually have to admit that they attempted to create voter fraud...

Also, why are they only looking for voter fraud in one direction? It works both ways...
