Being rich doesn't keep you from being crazy.
No BEING rich doesnt, but BECOMING rich and wildly successful in several areas of endeavor demonstrates that one is unlikely to be crazy, but instead is very analytical, cunning and adaptable among other things.
Why do liberals like yourself have such a difficult time in facing Reality instead of living in this made up 'I want to think it is therefore it is' kind of delusion about those who oppose you?
I'm certainly not saying everyone that get's rich is crazy but there are plenty of examples of those that are. There's Howard Hughes, one of the richest men in the world in his day who spent months in a darkened screening room without bathing, relieving himself in bottles and subsisting on a diet of chocolate bars, chicken, and milk. There's Ingvar Kamprad, founder of IKEA who steals sugar packets in restaurants, buys wrapping paper after Christmas to save money, often dresses a pauper, is tied to a fascism government movement in Europe, and believes space aliens are in contact with him.
However, I never said Trump was crazy. He just acts like it sometimes. His proposals such as barring all Muslims from entering the country and deporting all illegal immigrants are not practical. His claims of these actions being easy, legal, or having strong public support are delusional but they do serve his purpose of keeping his name in the headlines. If he were really serious about these proposals, you would see them documented on his official web site but they aren't. There's nothing about terrorism, Muslims, deporting anyone except felons and criminal gangs.
