Bro when you mail in that many only one is counted. The rest are rejected. I found it hilarious that when ballots are rejected for fraud. That is evidence of fraudulent votes counted. It just means that the system is working and rejecting fraudulent votes
This is unless the names are all different because you are mailing them in for yourself, all your "brothers and Sisters" and all of your "Cousins" or those who are illegal immigrants or felons.
