If billionaires support your political candidate it is because that candidate represents their interests. You do not share interests with billionaires. There are no good billionaires, you cannot be a good person and become a billionaire. You have to constantly hurt people to be a billionaire and billionaires support candidates who perpetuate their ability to hurt people. Republicans strongly advocate for hurting people and not having to hide that they are hurting people. Many billionaires are tired of hiding that they like hurting people while some billionaires think that is bad optics. This is the main reason some of them support democrats. They think it is bad optics. That is all. Republicans having broader support from billionaires only reflects that some billionaires don't think they have any reason to be ashamed and that they want a portion of the working class to join in on hurting others.
