@NZedAUS I think that you are focusing on Trump and missing the larger situation: it's not about what Trump has left or what he says, it's about his supporters projecting onto him.
What he has isn't fear and racism; it never was. What he has is a significant swath of US voters who feel disconnected from the federal government and see in him a vessel to express their discontent. Plenty see him as a way to set fire to the institutions that they feel have let them down.
All Trump has left is fear and racism? No. What he has is a crowd that uses him to vent their discontent.
