Theory is that they have had the ability to track currency for years but I never really believed that. I think there is probably some technology for tracking that could be used on that type of stuff but I really cannot see it being able to be carried out on such a scale. I'm sure it would be cost prohibitive and impossible to execute on such a massive scale with much secrecy beforehand. Maybe track bulk shipments of the paper but individual ballots, Idk? If it is true, be prepared for lawsuits from the left arguing that it violates the 14th Amendment on illegal searches or something like that.
