An eastern German region is voting in an election that could bring to power the first far-right state government in the nation’s post-World War II history. The vote for the state legislature in Saxony-Anhalt, a region of 2.1 million people west of Berlin, has gained outsized prominence because it represents the best chance yet of a governor’s post for the far-right, anti-migration Alternative for Germany, or AfD. That would be the biggest prize in the party’s 13-year history, at a time when there’s widespread discontent with an unpopular national government that has yet to persuade voters it can get the country’s sluggish economy moving.
