Dude absolutely just likes how buzzy the word coup is. Like, saying it's not fair is one thing, even though it very clearly is. And even suggesting it should be against the rules is a valid opinion, even if it's not based on facts.
But calling it a coup, not even an attempt at a coup, is silly. Even if she used a private army to storm the DNC to secure the nomination, it's not a coup until she gets inaugurated.
I don't have a square to spare!
