Correct me if I'm wrong, but there have been no resignations or party switches in this Knesset so far, have there? It's the same 120 people and the same party standings as when they were first elected. That seems pretty remarkable.
Although I did read a little while ago that Moshe Feiglin isn't taking the Likud whip.
It's too early for floor-swapping. Feiglin, and former speaker Rivlin are both running a pretty independent agenda. Livni and Benets' parties are at each other throats. Netanyahu is very suspicious of Lapid and is downright hostile towards Benet. with numerous incidents this coalition is creaking.
