a vast majority of Greeks want elections held more or less immediately. I also note that between them, Syriza and the GCP have roughly 20% of vote intentions in those same polls, ahead of PASOK when seen together.

I suspect there is also quite a lot of volatility in those numbers given that polling in Greece also suggests that "Don't know" or "Nobody" are polling, between them, in the 30% range.

Given Papademos is losing legitimacy as quickly as ipecac syrup tends to have one lose one's cookies (and the metaphor seems to me to be apt), what do the facts on the ground in Greece portend for a democratic rejection of the IMF and the EU?
