Greece: Polls show 2 main parties in dead heat before election

A municipal worker sets up a ballot box among other election materials at a school's classroom, in central Athens, Friday, Sept. 18, 2015, that will be a polling station for Sept. 20 elections. The box reads in Greek: 'Ballot box'. It is the third time this year Greeks will be voting, with the economy still in dire straits, a quarter of workers jobless, and capital controls limiting cash access to savings to 420 euros ($470) per week.
