Hat tip to ICSR's Insight article 'Who are Greece’s new fascists?' after the electoral success by Chrysi Avgi (Golden Dawn):
which gained 7% of the popular vote and 21 seats in parliament.

Golden Dawn is a fascist political party and a street movement with an occasionally violent history....Golden Dawn, therefore, is ingraining itself into the social fabric of the country and its success must not be written off as a temporary protest vote. Though its share of the vote remains small, its infrastructure and presence on the street is extensive.
This passage struck me as rather odd, particularly that such information was gained in exit polling:
Most disturbingly, exit polling shows that more than half of the country’s police officers voted for the party.

Surprisingly there is no mention of an active extreme left-wing, violent minority, who are not averse to attacking the centre left-led trade unions and of course the police - as seen in newsreel for months. IIRC the Greek Communist Party polled more votes than Golden Dawn.
