Considering the record of Greek pollsters, as well as their close affiliation with the two clientilist parties, I think a better measure of when Syriza became a credible threat would be the shift in the propaganda from "there is no alternative" to "Syriza is not an alternative."

To be blunt: If a Greek polling agency about whom I knew nothing else told me that a majority of the Greeks believed that sky to be blue, I would email talos and ask him whether the result was credible before believing it.
