In 2013, the "Alternative for Germany" started out as a soft-eurosceptic vehicle for disappointed centre-right voters and politicians. Since then, it has changed beyond all recognition. In a recent contribution for Electoral Studies, Carl Berning and I trace the changing motives and composition of the AfD's electorate using data that span the whole of the 2013-2017 electoral cycle. Our main finding is that anti-immigration sentiment, which had no effect on the AfD vote during the first two years, is now by far the most important predictor.
