Reuters reports here:
Syriza was supported by 23 percent of those polled, with the conservative New Democracy party second on 19.5 percent, according to the survey, carried out by pollsters ProRata and published in Friday's Efimerida Ton Syntakton newspaper. ... Popular Unity, the party formed last week by Syriza rebels who oppose the bailout, was backed by 3.5 percent in Friday's poll - just above the 3 percent threshold needed to enter parliament. But the Independent Greeks, the ally in Tsipras' former coalition government, scored just 2 percent, meaning Syriza would be forced to seek another coalition partner. ... It also showed 25.5 percent of voters were still undecided, making them the biggest bloc.
What nobody talks about in these reports, of course, is that the party polling third is Golden Dawn, well ahead of Syriza breakaway party Popular Unity as well as the communist KKE. Golden Dawn has increased its support from earlier in the year no doubt because Greece is being overrun by refugees from around the Mediterranean and the incompetent left running the show is failing to solve the problem. Golden Dawn is said to draw its support at elections from members of the police and the military.
