Just one of the ways, mail voting gives the rats multiple ways to cheat. For example toss just enough ballots from all the right zip codes and you tip 3-4% of the overall votes to the rats. That would have more then enough to take Trump out in 16.
Just figured it out for this state FL. If they got 400 votes per county they end up with over 26,000 votes. In a swing state like here then there is a major problem plus the rats get illegals, and the dead to vote. Lets not forget the homeless too.
