You've got dumbass libertarians and conservatives acting like he is awesome despite endorsing policies they hate.
You've got confused people thinking he's anti-war.
And you've got a lot of dudes inadvertently thirsting over him.
And all of this has a touch of Russian disinformation and conspiracy theories sprinkled all over the place.
Also, 99% of RFK stans are literally never going to actually vote Democrat, even if RFK was the candidate, they'll just be confused as to why Democrats are rejecting RFK in disgust. "Why don't you like RFK? I love him!" "Yeah, buddy, that's sort of why I don't like him, the fact that he's big enough of a clown that you think he's cool."
