Here are five quick reasons why Kadima cannot replace the Labor Party as the backbone of the Israeli peace camp:
1) It is led by a leader, Tzipi Livni, who has confessed that she doesn't like politics and feels that politics is like a sewer. Here is Ha'Aretz's take on that revelation.
2) Tzipi Livni barely beat out Shaul Mofaz for the leadership of the party in 2008. Mofaz has in order three ambitions: a) take over as Kadima party leader; b) replace Barak as defense minister--his old job; 3) replace Netanyahu as leader of the Right.
3) In order to nearly keep its same strength in the 2009 election as in 2006, Kadima had to cannibalize Labor and Meretz. This has left it incapable of leading a coalition on its own.
4) Kadima has no core principles or ideology--it was founded as a party of convenience like the Center Party and the DMC before it. It has avoided their fates simply because it was much more successful at the polls the first time out because of Sharon, who is permanently gone.
5) Kadima's potential Palestinian peace partner is Fatah, which is as conflicted as Kadima.
