So, if these are not super secret ballots and anyone could print them off, what about the fact that both the ballot and stubb must both have the tint and water marks, could these be matched up and who holds the stubbs once the ballots are deposited. surely both will have a number to match up the ballot to the stubb?
''The watermark for the November 3, 2020, General Election, is the CA Poppy. The tint
for the background and watermark is Red PMS 192.
The watermark and tint must appear on the ballot itself, not only on the stub
