Sorry - I am not clear on any of the Israeli governmental situations. Maybe others can answer your questions.
The Arab parties (13 seats) have endorsed Netanyahu's rival Benny Gantz.
First time the Arabs have done that in three decades.
Apparently, they hate Netanyahu so much, they broke their long tradition of never endorsing a Prime Minister.
The election estimate is now Gantz at 57 seats, Netanyahu at 55.
A majority requires 61.
From the AP: “Maverick politician Avigdor Lieberman, head of the mid-size Yisrael Beitenu party, controls the final eight seats, making him the key power broker.”
Lieberman says he will not endorse any candidate, but I'm not sure what that means for his seven colleagues.
