If you've forgotten your recent Israeli political history, Kadima was established by Likud politicians, ministers, who while running the country totally rebelled/deserted/contradicted the Likud platform and ideology in proposing and promoting Disengagement, the destruction and upheaval of Jewish Life and communities in Gush Katif and a couple of yishuvim in the northern Shomron. They fled Likud with their tikkim, ministries and positions, attracting other Leftist political opportunists. The three wheeler-dealers who orchestrated their big successors are no longer in the picture.
- Ariel Sharon has been comatose for years
- Ehud Olmert was forced out of the position of Prime Minister, because he's facing multiple charges of corruption
- Tzachi Hanegbi had to leave politics after being convicted of corruption.
So, it's pretty clear that this primary is more like a tournament consolation game for third place.
