Jeremy's Knesset Insider 
Once Gantz declares his manifesto (presuming he does not mess up big time), I predict that Orly Levy will become his casualty.
Do you think Gesher will join the coalition?
I hope not. Orly Levy is a nutcase.
It will very much depend on what Geshers demands are likely to be and how many seats Likud has without her. It is not necessary up to her.
It is very early days and as Harold Wilson said a week is a very long time in politics. Gesher might not even make is. As the song says “Gesher T’zar Meod”
