Trump unsupporters only have his words to go by. We cannot read his mind or his intentions. In that regard I admit we are very limited. What in the world would we do without all his supporters acting as his interpreters? How would we survive?
How do any politician know that. We are all good at ascribing evil intent to other people, occasionally we are even correct in doing so, but usually not.
- "Mom hates me and want me to suffer, she forces me to eat broccoli". (Nah, she has just been reading nutrition advice from evil experts who want everyone to suffer ;-) )
- "It was just a golddigging ploy when she said she loved me. All she wanted was my money".
- ... ad nauseam.
