WHEN deciding whether to grant citizenship to an outsider, the Ancient Greeks would put the matter to a vote, tossing coloured pebbles into a clay jar. On June 17th almost 29.7% of voting Greeks picked the colours of New Democracy, a centre-right party that broadly supports the country's EU bail-out agreement. It was seen as a vote to remain citizens in good standing of the single currency. New Democracy narrowly beat Syriza, the "coalition of the radical left", which was threatening to rip up the bail-out agreement.
