German election

Angela Merkel is in trouble because traditional conservative voters backed the Alternative for Germany opposition party, which collected almost 13 percent. The AfD ran against mass immigration and reflected the cultural alienation of many voters.

For the same reason you had Labour-party voters going for Brexit and Obama voters abandoning Hillary, politics in Western countries is increasingly not about Left v. Right but about Ins v. Outs. If you are part of the elite, you have likely backed policies that the working class thinks hurt them.

There is a lesson for Republicans in the results of the German election that effectively reelected Chancellor Angela Merkel.
