Insane Clown Posse communicates like the part-time wrestlers they are. Like the WWE superstars they grew up idolizing and emulating, they have mastered the art of making fans feel like they're talking directly to them. Trump has a similar gift, to the point where if the media simply runs a clip of him talking at a rally or a transcription of his words, his supporters feel like they're still somehow distorting his message.
Pop Quiz: Trump rally or Juggalo gathering?
The president-elect's manner of communicating with the public isn't sophisticated. It isn't smart, let alone intellectual. It's sloppy, repetitive, crass, and self-aggrandizing. But that doesn't mean that it's not also extraordinarily effective. To his acolytes, it almost doesn't matter what Trump says. It doesn't matter to them that by just about every possible criteria other than his own, he might be the one of the most dishonest people ever to win a major party's nomination for president. No, what matters to Trump's die-hard followers is that Trump's casual, off-the-cuff style of speaking feels like someone speaking candidly from their gut.
Almost if he doesn't give a shit about who he's talking to?
The fact that Trump continuously seems to be improvising badly in the moment rather than working from a script or a teleprompter adds to the sense that Trump is "real" in a way polished veteran politicians are not. Even the infamous Access Hollywood recording fed into this conception of Trump as a guy who talks like an average guy, rather than one of the lofty elites who waste everybody's time and energy by "thinking" before they speak.
Insane Clown Posse's style of communication has similarly been mocked far and wide. Shaggy 2 Dope's insistence of inserting a "fucking" before the word "rainbows" on the single "Miracles" has been ridiculed since the moment it dropped. Yet Juggalos and Deplorables love the idiosyncratic ways their heroes communicate. They associate their bluntness and simplicity with honesty and directness, and the thoughtfulness and verbal sophistication of Trump's opponents and Insane Clown Posse's rivals with dishonesty and obfuscation.
