Jeremy's Knesset Insider 
I wonder if they really care if the polls are accurate; maybe they just want to publish something cheaply. Or I suppose they only care about the big parties.
I reall one poll, I think in Idiot (well, that’s how it used to be pronounced) where the commentary contradicted the actual results.
