Germany stands at a threshold this weekend that has not been crossed since the ruins of 1945 were still smoldering. In Saxony-Anhalt, voters may hand the far-right AfD an outright parliamentary majority — the first time a party of that character would hold state-level power in post-war Germany. The moment tests not only the durability of the Brandmauer, the political firewall that has contained the far right for nearly eight decades, but also the deeper question of what happens when a movement built on grievance must finally answer for governance.
