I think they will still try, and that is why we have south American criminals marching to the United State in order to try to block vote law enforcement on election day.
You don't need to import new illegals to perpetrate the 'Rat vote fraud schemes. There are enough here as it is, unfortunately.
This new "caravan" of illegals headed toward the Mexico-US border will probably not arrive at the border until AFTER the election is over. Their very existence in news reports can only HURT 'Rats in the elections by bringing out more pro-Trump voters.
The purpose of the illegal caravan is not to vote, it is to tie up immigration control personnel. They can’t be in two places at once.
