True, that lowlife cost Shas a seat, however I do not think it is crucially consequential. With Shas having one more seat, UTJ would have been in the position of either taking responsibility to sabotage the option of a right-parties’ coalition and enabling the left to form a cabinet, or accepting responsibility of supporting a govt voting laws that limit exemption from draft to the illuim (while, of course, granting exemption to Arabs, xian clergy etc etc), cut support for yeshivot, limit (further) the state benefits for those who did not serve in the army, and so on. Both options are difficult. Yes of course the current option is difficult too.
I am afraid before there will be new elections, a draft law will be voted.
