I think the ballots were marked after ppl voted.  How else would the sting work.  If 80 million ballots were all mailed out in advance of election day and all of them had the water mark then you would not be able to tell what votes were returned before the deadline and what was returned after the deadline.  The only way to do that is if the ballots were marked when they were received back.  The national guard was in place in 12-16 states depending on the source.  They were to assist with election security. It makes sense they marked the ballots and Steve Pieczenik brings them up when he talks about marking the ballots.  But its not clear or explicit.
