"The GOP doesn't make it clear the GOP owns[sic] . . . the property.  They claim it was party property, which Miller was part of when he received the papers."
Where do you see see any claim by the GOP or Miller that he received the fliers prior to 2016?

"GOP does not say "stolen", but that "had been STOLEN" . . ."
I cannot take you seriously any more.  It seems because they quoted the entire legal language which included "stolen" and you still missed it.  I assume it is not a failure of reading comprehension but a failure of thinking.
