More than five years into the eurozone crisis, Greece is at the center of attention once again. On Dec. 29, the Greek government announced that it will conduct early elections Jan. 25. The decision came after the parliament in Athens failed to appoint a new president. According to the Greek constitution, the parliament has to be dissolved if lawmakers fail to elect a president. This opens a new period of political and financial uncertainty that could ripple across the eurozone. Greece is currently ruled by a grand coalition of the country's traditional mainstream parties — Prime Minister Antonis Samaras' center-right New Democracy and center-left Panhellenic Socialist Movement, or PASOK. The formation of this coalition was an unprecedented event in modern Greek politics. It was the result of two inconclusive elections in 2012 that forced Greece's traditional rivals to form an alliance to remain in power.
