That's not to say that the four biggest states can be had. NY, CA, Tex and FL is all one needs to change the outcome of the election.
And anyone from the outside or anyone from the inside can attempt to do it. We have to be diligent, trusting no one. All precautions have to be taken.
One of the reasons why I don't like pre-voting or multiple days to vote. it should be all done on the same day to illuminate as much fraud as possible.
All fraud can't be stopped.
