The only time your going to get a party like that is when a substantial number of Jews decide they want to abandon the concept of a Jewish state in favor of a binational religion free country. Meeretz is just a far left party rather than a party that promotes the kind of ideals this kind of state would be and haadash is just a Jewish minority who love arabs it's not a party for all. There is not enough support for any kind of party like this in the Jewish sector and the bulk of the arab party voters will continue to vote for arabs because their priority is not about arabs & Jews together it's about what's in the best interest in the arab sector THEM & US not all together Istael is and always has been a politically divided society. Of course is Avraham Burg is conviced there is a demand for such a party out there then nobody will stop him forming his own party which runs on that platform althoughI have a feeling it won't win a single seat because there is no demand for it amongst the voters.
