VIENNA, AUSTRIA - MAY 22: Norbert Hofer, presidential candidate of the right-wing populist Austrian Freedom Party (Freiheitliche Partei Oesterreichs, or FPOe), greets supporters at the FPOe election party following initial poll results during Austrian presidential elections on May 22, 2016 in Vienna, Austria. The FPOe is facing off against the Austrian Green Party and its presidential candidate, Alexander Van der Bellen. The FPOe's recent success is part of a larger trend across Europe in which right-wing parties have gained ground, in part due to public unease over the large influx of refugees and migrants over the past year and a half.
