Micro,
Great morning to you as well.
Regarding "watermarks" - while we do not know how/where/IF they were implemented we DO KNOW that they indeed are part of the CISA aresnal per the CISA website itself. I posted this a few days ago.
"While the specific measures vary, in accordance with state and local election laws and practices, such security measures include signature matching, information checks, barcodes, watermarks, and precise paper weights."
