If I watched my country invaded by migrants invited in by a leader who did not have the moral or democratic authority or right to do this, and watch as these migrants attacked German women, engaged in violence and terror attacks, yet fed freely at the trough of the welfare state, I would vote for the AfD, despite my misgivings about some of their origins. 

What Merkel did changed Germany and Europe forever, for the worse, and we are only beginning to see the consequence now.  Fast forward 30 years, and Europe will be completely unrecognizable.
