Seems difficult to do. You'd need to know the name and address of the voter, and be sure that that haven't voted yet, and won't try to vote after you.
I can see that happening maybe a few times, but it seems ineffective on a large scale.

If they already voted? "Oops, I forgot."
If they haven't voted and come in later, so what? You're long gone.
