Take a look at all the cases of voter fraud in elections going back years and years. Instances where people went in to the voting booths and pretended they were someone else in order to vote more than once amount to about ZERO PERCENT and have had next to no effect on election results.
If however you look at all the instance where Voter Fraud (also now called Election Fraud) was not committed by the Voters but instead by the Counters and Harassment Groups – you see all the instances where their crimes have skewed results heavily, over and over again. When the counters throw away ballots, introduce fake ballots, rig the machines, break machines, harass voters, mislead voters, and so on.. those are the election crimes that we need to concern ourselves with because THOSE ARE THE CRIMES BEING COMMITTED. And those crimes destroy democracy.
