Because giving the right to vote to the citizenry is sooooooo unlike giving the right to vote to the citizenry?
Face it, if there was never an American Revolution there would never have been a Marxism. The only difference is here we had a neu-Aristocratic class who (reluctantly) progressed to allowing a republic with a vote limited to only monied land owning adult male WASPs for selecting representatives for a parliament as opposed to a concept calling for 100% democratic rule where the public contols all apparatus from govement to economy.
In the meantime, so-called Conservatives have become increasingly open about their autocratic leanings (after all, going back, real American Conservatives favored Monarchy. When they weren't able to maintain that link with Britain, they sought to crown George Washington). As there is currently something of a shortage of anyone with royal roots going back to the beginning of the USA, they opt for an Autocratic type. Hence their zeal for a wannabe dictator like Trump, and their admiration for the likes of Putin and whatever other self-adulating nutters in that soup. It isn't exactly an accident that the Jr Consevative set in particular can be given to festooning their walls with pictures of Hitler.
Hitler, btw, was not a Marxist. He sought to extirpate them from his party, from Gemany, and then from Spain and Russia. In fact, that was the excuse for people even here to like him, that he and the Nazis were a bullwark against the spread of Communism. Hitler was a Nazi. Those who idolize him are neo-Nazis. If they don't like it, imagine how the rest of us feel about their putrid stench?
