Being called socialist isn’t even the issue. My point is that a news monolith has spent decades radicalising half the country and at this point there are enough cultists that will mercilessly tear down anybody Fox&Co paint a target on. Until there is a solid defense against such a hate machine, no party will flourish on its merits as long as Fox-drilled stooges will only be fed a caricature of any opposition Fox designates as the enemy. Even your perfect ideal candidate would lose the election. The boogeyman Fox would paint them to be would be so repulsive and half the country would never even hear their ideas anyway, except what skewed perspective Fox would blast the viewers with 24/7.
Technically, the US also has protections against wannabe dictators claiming they are above the law: a supreme court which, were it not undermined by that dictator’s toadies, should shut that shit down in a second. Still, there’s a difference between blindly following everything that court makes up out of thin air and supporting the actual rule of law. Same with democracy.
