UPDATE: It looks like a binary choice between New Democracy (in favour of the bailout package including spending cuts, privatisation AND unfortunately tax rises) and the Green Party like Syriza Party which essentially expects to blackmail Germany into paying for its retention of socialist economics. New Democracy retains a chance Greece remains in the Euro, Syriza is highly likely to see a complete default in late July if it can't convince the Germans to prop them up.
It is entirely plausible that neither could form a government.
That's why it remains the most principled choice to back the Liberal Alliance, for only it will support both less spending and lower taxes. New Democracy may be less worse than Syriza, but if economic growth matters to anyone in Greece, they can't get it voting for for those who support higher taxes (let alone a bunch of reformed communists).
