Kadima was formed for momentary reasons. It exists today becasue there are a large number of voters that do not want to accept any significant Israeli wrongdoing, do not really want the necessary compromises but still see themselves as "pro peace." This is mirrored on the Palestinian side with people who also see themselves as "pro-peace" on condition of return to 1967 borders, return of refugees and renouncement of Zionism. It is in fact, the most unrealistic voter.
