Polls have the two sides evenly balanced. There are no public data that break down the demographics and the inclinations of “yes” and “no,” but conversations around this city depict a populace that is split in two: Haves and have-nots, young and old, those bitten by austerity and those less exposed, those with money in the closed banks and those without. Whichever side wins and whoever is leading Greece next week, next month or next year, the gulf will be hard to close.
