The decision to go all-in with the right-wing bloc was based mostly on three assumptions. The first is that this is the bloc with the most potential for growth.
The second is that the voting public is much more connected to the right. And the third is that Netanyahu is completely dependent on the ultra-Orthodox. The decision is understandable, but it is not enough. The Haredim have much more to gain from being a balance sheet. They will not lose many voters, and the few who switch to other parties are worth giving.
