Obviously Insane Clown Posse's bread and butter is rust belt America so you're def. gonna have an overlap.

However they are decisively counter-culture; pro drugs, pro weed, and they are in DC to protest them getting categorized as a terrorist group so they are there explicitly for anti-government reasons as opposed to Pro-Trump people. Add to Trump's nazi debacle...I think its going to end up being a counter-protest. Not like Charlottesville tho; despite them trying to portray em as scary they are basically trailer park hippies.
