The most disturbing is in fact LAOS getting a second seat and 7%.
The most disturbing is that this looks like the entire Green vote came from people who would have voted Syriza. I DEMAND A MERGER!
I may be wrong about this (if someone from Greece knows more about the issue I would be happy to hear what they think), but from what I understand much of the Greens' polling strength came from disappointed ND supporters who ended up voting for LAOS after a video came out where the leader of the Greens was caught saying that FYROM should be allowed to call themselves whatever they want and that Greece should honor Kemal Ataturk (the founder of the Turkish nation who was born in Greek territory, but isn't very popular in Greece because he is considered responsible for the massacre of the Greek populations in Asia Minor). I assume some voters might have also gotten confused because there were several Green parties on the ballot and 2 other Green parties received approximately 1% each.
SYRIZA from what I understand lost much of its strength for 2 reasons. The first one was their opposition to the construction of a mall in Athens and the ongoing legal battle has delayed the construction of a soccer stadium, which has angered the fans of the team that would be using it. The second one is because they are considered responsible for the vandalisms that took place in December. SYRIZA is my favorite party in the greek parliament because they're the only ones that support gay marriage and fight for environmental issues, but they don't really have a base and the low turn-out hurt them. Their leader actually asked the Greens to cooperate after the elections, but I doubt it will happen, as the Greens are not very fond of the far-left factions within SYRIZA.
