If you see AP, SP, SV, MDG and R as bloc and H, Frp, V and Krf as one. Yes then the first bloc got 49.3% and the second 48.9%. However MDG does not see them self as part off any bloc and SP is a non socialist agrarian party that has historically guverned with Krf and V and with H as well. You also have to take in the non socialist micro parties Kristne which got 0.3 and Liberalisterna which got 0.2%.
Also the government bloc symbolically gets 50% if you consider the smaller rightwing parties: pension party: alliance, coastal party, christian party, liberal party has 1.1% combined.
