A constant refrain has been there is no voter fraud because prosecutions are very rare. Basing whether a crime has been committed on the number of prosecutions is problematic. Using this logic there was no fraud in the financial crash since very few people were prosecuted. The amount of prosecution is more closely correlated with how hard you are looking for something rather than how much of it is happening.
Voter fraud lessens each of our right to vote. It will destroy a democracy, because people will lose confidence in their vote. Even a small amount of voter fraud can determine the winner in a close election. It also can lead to electing politicians that will feel no responsibility to represent to the people since the people did not elect them.
One of the precursors to voter fraud is fraudulent registrations. If people are registered who don't know it or do not exist, the perpetrator avoids one of the major risks of voter fraud. This is the risk of someone showing up to vote after you have already fraudulently cast their ballot. This is one of the only ways voter fraud will come to light. If the voter does not exist, they will not show up to vote.
The only way to determine the extent of fraudulent registrations would be to contact every registered voter and determine if they indeed registered themselves. The only way to determine if voter fraud was taking place would be to contact all the people who voted and determine if they actually cast a vote.
Beware of anyone telling you that there is no voter fraud who has not undertaken these steps. They are expressing their opinion.
