It must work, but why?

The Trump cult email spam continues along the same lines. It’s not political or economic in any way. Nothing about borders or walls or jobs or China or Israel. It’s all pure whipsawing emotions, like an obsessed menopausal ex-wife.

Today’s subject line: “I would never have expected this from YOU, of all people!”

Marketers must know why this works, otherwise the cult wouldn’t be doing it. The approach certainly doesn’t work on me, and presumably I’m in the target demographic.
