No but he could become the man behind the throne. Sometimes that person effectively has more power without the responsibility.
Elon is such a mixed bag. He'll do one thing that is wonderful. He has talked about helping Trump cut the federal government by 80%. That sounds wonderful, but he has done and said other things that show he likes government handouts and has some tyrannical tendencies. I never know what to think about him.
Maybe Elon and Trump are made for each other. They both have some really good traits and some really bad ones.
