Greece is preparing this morning to vote on drastic austerity measures that have sparked nationwide strikes and rioting in the country's capital, Athens. 5,000 police were deployed to Athens over the past two days, to combat protesters with tear gas. Meanwhile, the climate inside Parliament is calm as they prepare to vote. If the austerity measures pass, Greece will be able to obtain a second bail-out from the European Union, and avoid defaulting.   Rachel Donadio, Rome bureau chief for our partner The New York Times, speaks with us from Athens.
