Why does Adele even care, she lives in high tax England. Do US politics really interest her at all.
By the way she has a complete sold out USA tour coming up very soon. It’s all PR and she is getting new fans and exposure.
I doubt that Adele does care about politics in U.S. Most likely this is being driven by the leftists that handle her business dealings over here. They probably told her it was a bad idea to have a conservative politician playing her songs at his rallies. Probably also told her that Donald Trump was the U.S. version of Margaret Thatcher, likes Winston Churchill and once tried to arrange a date with Princess Diana. And that’s probably all she needed to know.
