California is “special”, according to Q. I recall FreeQers saying that the troops POTUS sent to the border with Mexico wouldn’t be there just to keep people from entering - they would also keep people from LEAVING the US. And, well, if someone thought rioting would be a good idea...the military could handle that too - given the status of “state of emergency” in force.
So the affidavit, and evidence collected from others across the nation documenting cheating by the Dems, could have been used to open FISA investigations on the cheaters and organizations. The affidavit is dated 3 days prior to the 2016 election re absentee balloting, so they may have begun collecting intel prior to the 2016 election and then traced the money and connections following it. With proof of that kind, they could renew the FISA ahead of the midterms and collect away. They could. :)
I just learned something the other day - posse comitatus does not apply to the Marines.
