Before I get to your question...that's a really weird definition. I mean it excludes most stereotypical fascist regimes, like nazi Germany for example. A communist revolution wasn't really on their list of fears or even concerns. In Weimar Germany they even shared voters. Most communist party voters became nazi voters once they became a thing, they run on the same platform. It's in the bloody name, Nazi = National Socialism. This definition seems to deliberately only target America, the US is the only one that goes fucking ape-shit when socialism let alone communist is at all mentioned.
Anyways, to your question. We weren't really talking about presidents specifically, tho most of them fit the bill. Both democrats and republicans say the fucking "you're with me or against me" shit, like really??? The US generally has a rich history of violently shutting down competing powers, be it domestic or abroad (a 2 party system IS NOT natural for a democracy!). American imperialist wars are pretty much build on forcefully spreading American culture at any cost (especially if it involves killing anybody claiming to be socialist or not christian). From a young age US citizens are indoctrinated, the shit where they swear loyalty to the flag every morning is creepy as fuck, also the flash everywhere. Like christ, just look at how Americans treat foreigners. Didn't even mention the police yet...
