The Greek people had a difficult decision to make. They had to choose between two diverse groups of parties: a group of moderate parties from center-right to center-left which gave first priority for Greece to stay in the euro zone and renegotiate its bailout terms as far as this is realistically possible; and a group of extremist populist parties of ultra-left and ultra-right, giving their first priority for Greece to free itself from the bailout terms even at the cost of losing its euro zone membership status.
