Otzma also made a mistake here by not forming some kind of technical bloc with the right. They ended up well short of the threshold and wasted a ton of rightwing votes into the trashbin.
Bibi is now saying either make me PM in coalition or form a govt with the Joint List. He's trying as hard as he can to get a unity govt with Blue&White and convince them to make him PM, IMO. Not sure if that's going to work.
