You’ve got to be kidding me…It is nearly impossible to cheat on a large scale in an American election, that's correct.
You'd have to figure out who didn't vote and then create fake ballots for those folks after the election closed and before the votes were counted. Seems nearly impossible.
The method of voting most subject to cheating is mail in, but you'd have to find people who weren't voting and just buy their ballots/pay them to vote a certain way. Good luck with that.
The lib big cities had it all down…. Boot the R’s from the vote counting facilities and run the van loads of fakies through the compromised voting machines. Very, very easy.
