Honestly, I think this might be on to something. RFK jr was not always a lunatic - before he went insane he did some truly great things in his career. He then gradually made a turn for the worse, ending up as the mentally insane candidate we know today. It honestly explains his political platform pretty well.
It also reminds me of that great infowars interview with a Sanders supporter (correctly?) observing that they have worms in their brains.
