In days of yore, Trump would be deemed an "eccentric". Which is code for, "rich lunatic". Eccentrics were locked away at home or posh "resorts", while less well-to-do citizens were relegated to asylums. He is, put simply, a huckster a carnival Barker (sorry barkers). It's not like he made his money honestly. He put together a functioning criminal enterprise designed to fleece the public. He got there through bribery, extortion, and outright fraud. But, his voters "like what he says" because they are idiots, sycophants and bigots. It really is that simple.
