Practice and trials of techniques for 2020.
Remember those letters from the county recorder asking if the named individual was still residing at the address?
Now, the kicker.... The departed individual was supposed to mail the letter back to the county.
Now, how stupid is that?
The named individual (voter roll) has moved, died, departed, ain’t there.... BUT, THAT PERSON IS SUPPOSED TO MAIL THE LETTER BACK TO THE COUNTY TO TELL THEM THEY ARE NOT AT THIS ADDRESS !!
Doomed to failure, but does provide a clean list of phantom voters.
