You can delude yourself all you want. It is normal for Trumpers to do that. They live in a world of their own. Typical cult mentality.
By the way, "no", I am not a fan of Taylor Swift. I am 79 years old and I am a fan of people like Johnny Mathis, George Benson and as far as current artists, I am a fan of Adele.
Having said that, in this day and age and considering people like you( that buy what Trump is selling), the reality is that artists, athletes and other well-known media people (like Trump) help sell an idea or a product big time.
For example, do you have any idea of how much Michael Jordan helped Nike to become a well known and successful brand?
Let me just say that Michael Jordan Brand of Nike shoe has earned Nike $19 billion is just 5 years.
In addition, do you know how much the candidates for presidency spend on advertising their own images? well, lets just say that at least 1/2 Billion dollars are spend in advertising. Most people do NOT think or evaluate things as they are (you are a perfect example of that). Most people buy what they are sold without thinking of whether it is best for them or not.
As such, getting an endorsement from TS will give Kamala a bump up and Trump saying he hates TS will give him a bump down.
That is just fact, even though you try to wash it away. This is reality and there are hundreds (if not thousands) of examples I can give you, where people were sold a "bill of goods" and they bought it without thinking twice.
