Again:
1. Trump's most popular policy among his supporters *by far* are his "immigration policies"
2. His immigration policies are by definition, ethnic cleansing policies. They were devised by white nationalists who self-described their sole purpose as "turning the USA into a white ethnostate."
3. White American voters are the only group of US voters that support these ethnic cleansing policies at more than 50%. Black, Asian, non-white Hispanic, and Indigenous people all reject these ethnic cleansing policies.
4. Trump supporters are willing to give up every other policy to make sure that this one happens, as they view it as existential. They are willing to pay to do this.
