They have been MASSIVELY trying to stop people from voting, what the fuck are you talking about you absolute nincompoop? They keep purging voters and trying to implement new ID requirements and closing polling places and encouraging people to "poll watch" (voter intimidation).
Have you heard of a little thing called The American Experiment?
Funny story. They actually were in on the ground floor of a new nation and they said, "We left this England place because it was totally bogus. So if we don't get some cool rules - pronto - . . . well then we'll just be bogus too."
If voting was actually a threat to totalitarians in power they would spend a lot of money and power to convince you that it's pointless and you shouldn't do it.
