Golden Dawn here in Greece is the Neo-Nazi party. It is not new party it exsist more then 30 years I think. Their usual number at national elections was at the range of 0,30%. The typical shaved head nazis that had connections with goverment.
Due to the economic situation here but mainly due to the large problem of illegal immigrants escpessialy here in Athens and since noone ever really cared, they took full advantage of it and now they are looking for a percentage of more than 6%. But I have to admit they played very well. For example if you are 70yo and want to go to the bank to get your pension but you too scared, you call their office a day earlier and they send you a "bodyguard" to help you with your transaction. If you have rent your appartment to illegal immigrants but they dont pay you and are not leaving you call them. They come they throught away the immigrants, paint the house and change the lock all for free And when you ask them what payment they want they say when they elections come just remember us.
Unfortunatelly the Neo-Nazi and far right-wing partys are in rise in Europe as they were in the 30's (Oh by the way after again a major economic event at the US). Unfortunatelly history repeats it self and people dont learn.
