How would anyone know that I am not giving the name and address of someone, other than myself, that I was sure was not going to vote due to any reason? By not requiring an id then I would be allowed to vote for who would know that I am using an alias. In this instance how would fraud be measured?, by your system the fraudulently casted vote wasn't fraudulent at all.
I personally believe these people claiming that they can't get an id is a farce argument just to allow continued voter fraud.
If showing an id is too much to ask someone , we shouldn't we use the precinct voter rolls as a list of people that are cleared to purchase a gun. They could just walk into a gun store, state "a" name and address. If it matches a name and address on a voter roll then surely it's legit, then sell them a gun. If not providing an identification is a good enough system to ensure the integrity of a person's vote then it should be good enough system to ensure a proper gun purchase.
