Having found a diagram showing the results of the last Greek election I was surprised to see how many voted for parties that failed to get past the 3% barrier for being allocated parliamentary seats. It was 19.03%, that is a big minority who are disenfranchised. Even more stunning when you learn the leading party is allocated an additional fifty seats.

Votes cast from Left to Right:

KKE (Communist) 8.48%
Syriza 16.8%
Democratic Left 6.11%
Pasok 13.8%
New Democracy 18.8%
Independent Greeks 10.6%
Golden Dawn 6.9%

It is remarkable IMO that the two extreme left and right parties polled so closely together. Not to overlook the KKE are reported to be an unreconstructed, if not Stalinist communist party. Extremes need each other.
