Hollywood has long been replete with rich idiots that think their expertise in pretending to be someone else qualifies them as political genii and worthy of emulating.
Celebrity worship is a plague on the US population. It warps the minds of many a starry-eyed fan that wishes they could be in celebrity shoes.
With exception of a scant few, the more famous they become, the less they care for the people that made them so.
To a lesser degree (I think), many entertainers follow the same patterns. They have a far more personal relationship with a live audience and can feel the love, so to speak. All the successful movie stars feel is the money.
