After counting the military and prison votes, Bayit Hayehudi gained a seat (and the Arabs lost a seat.) So now the right-wing has 61 seats while the left-wing has 59. So, technically, Bibi can form a coalition without Lapid with just Likud, Bayit Hayehudi, Shas and UTJ. Even, as likely, Bibi forms a more broad coalition including Lapid, it puts Lapid in a weaker negotiating position since the coalition could be formed without him.
So, perhaps, Amsallems costing Shas a seat wasn’t as consequential as first thought.
