He's not "extreme far right". He might be more right-wing than the average EU leader, but that's what you're going to get in a country that has been flooded with right-wing propaganda for decades.

Realistically, what matters is that in this election Hungary had a choice between Orban and not-Orban, and not-Orban actually won. Because someone else won in a relatively free and fair election, it's possible that the next election can be between a left wing option and a right wing option.
