Burgenland governor Hans Peter Doskozil will be the new leader of the SPÖ. He won 33.68% in the internal leadership election. It was a close result: 31.51% voted for Andreas Babler, 31.35% for current leader Pamela Rendi-Wagner. This means FPÖ-SPÖ probably becomes more realistic. On the 3rd of June, there will be a party congress to make things official - Babler and Rendi-Wagner are expected to accept the result according to Austrian state media ORF.
People have previously pointed out that SPD infighting and leader unpopularity are why they failed to rise off the ÖVP collapse, leading to things like the KPÖ gaining relevance and the FPÖ currently leading the polls. And this guy is new and supposedly popular. So I would be curious to see if voters intentions remain the same in a month or so.
Doskozil is not new, he's very well known in Austria. But he would certainly be a significant change from Rendi-Wagner. A former police officer, conservative in style, a left-of-center populist in politics. He has been able to transform his personal popularity into votes for the SPÖ in Burgenland, a narrow, mostly rural strip of land on the Hungarian border. It will be interesting to see if he can win meaningful numbers of new voters in the center and the populist quadrant on the national level, too. On the other hand urban and socially progressive voters might leave the SPÖ, but it's unclear how important they are numerically in the SPÖ voter base.
