Where was all the "voter fraud"?

During the recent mid-term campaigns, there was a lot of talk, most of it from the “Fox News” and some Republicans, of a potential for voter fraud. There have been a few instances reported, but I heard a statistic this morning that the actual cases of voter fraud alleged by either side amount to about .000007% (give or take a decimal place) of the total votes cast. Do you think this is because the original talk was something on the order of fear-mongering, or because the “extra efforts” by certain organizations resulted in “nipping it in the bud”?
