Coming on the heels of the U.K. general election, the Israeli general election, the Scottish referendum and the U.S. midterms, Sunday’s Greek referendum looks like the latest in a series of bad outcomes for pre-election polls across the globe. While the last few polls before the vote showed “Oxi” (“no”) ahead by just 3 to 4 percentage points, it in fact took 61 percent of the vote to 39 percent for “yes,” a margin of more than 22 percentage points. CONT.
