An interesting coalition possibility ...
If Netanyahu is deposed or resigned. If that happens, Labor could make a government with the following parties:
Labor - 20
Yisrael Beitenu - 12
Shas - 13
Yahadut Hatorah - 6
Likud - 11
This would allow the Likud and Labor to effectively kill Kadima. Kadima would not survive as an opposition party.
