Ok anons I think I’m into something. Forget the watermark noise. It’s all about the CoC (chain of custody) of the ballots. We were ready for this chicanery. IMB = Intelligent Mail Barcoding which enables ballot tracking. All of the one bubble fake votes for Biden will be tossed out because we will be able to prove that they were never mailed out in the first place. BOOM. This is from the CISA which falls under the DHS.
