Looks like the fix is in.
I really doubt it. As much as I tend to back Hofer (or frankly anyone over a Green candidate) I do not see why the system will block his victory. In fact, having Hofer win might make it more likely that PFO might implode if he were to mess up. The Prez in Austria is fairly ceremonial. If the fix is in it is most more likely they will do it in 2018. But if Hofer were to narrowly lose which he did in this case it will most likely energize the PFO vote in 2018 especially if the overall political climate does not improve.
In the same way I back Trump but ideally I want him to lose narrowly to Clinton. 2018 will be a massacre for the Dems in 2018 if Clinton were to win narrowly with no coattails.
Well, the energized FPO vote and chancellor Strache in next few years seem like a good chance. We'll see.
