In a lot of ways this had to happen. Americans have been screaming for a change and many felt fucked that no matter how they voted the system wasn't going to change. How do you send a message when there isn't a messenger? The politicians thought it was going to be the same business as usual and they are now confronted with a very resounding slap across the face of Americans are sick of their shit.
Sadly every lesson comes at a cost. Trump is going to be a painfully embarrassing lesson and hopefully we can stop the worst of his B.S., but it is a lesson we all need to learn. Politicians-sick of their useless B.S..America-sometimes the one that's telling it like you want to hear to hear it, is actually just doing what a great conman does. Either way this had to happen because Americans are tired of yelling to be heard.
