Correction: Help Likud.
Likud has two options: if it can gain two of three seats in the raw vote count, it can either form a narrow right-wing government with the haredi and religious Zionist parties or bolster the coalition by peeling off support from the centrist parties of Kachol Lavan.
A third option is a Zionist secular government of Likud, Kachol Lavan and Yisrael Beitenu excluding the haredi parties.
The fourth option are new elections. Last one is a last resort if all attempts to form a government fsil.
