It’s springtime for AfD. The anti-immigration party appears to have won significant numbers of seats in three more state legislatures today. With Alternative für Deutschland in half of 16 regional governments, it spells trouble for Cancellor Angela Merkel, the world’s most powerful woman. She ran the country virtually uncontested until eight months ago, then welcomed the first waves of more than a million illegal immigrants. That helped boost support for AfD, which is gradually siphoning support from Merkel’s conservative party. German journalist Dirk Kurbjuweit argues that we’re witnessing history: the birth of a new German republic.
