Well no one is going to win a majority are they?
No one ever wins a majority for anything on their own in Austria (not including municipal elections in some obscure small Tyrolean hamlets like
Gramais or
Hinterhornbach), so "win" in our context always means being the party with the largest vote share.
As for the question - I hope SPÖ, I fear FPÖ. If there's one golden rule of Austrian politics however, it's regardless of what happens, the FPÖ profits... Let's prepare for the worst and hope for better?
