To our foreign friends, I think most of us are trying to understand it too. The only explanation is that most americans are selfish idiots with no understanding of economics who somehow believe when an orange idiot tells him he will save them from a failing economy (the economy is great actually), they believe him.
It is the fatal flaw of democracy. If you let every idiot vote, they will. But fear not, they won't need to bother voting soon enough...
As a rich white guy, I'm going to be fine, but I weep for the shithole my country has become. Those morons think America is great. They are wrong.
