Let's face it: Aharayut Leumit (National Responsibility) was a mouthful. Kadima is probably better for a party name.
One prominent MK from Labour, Haim Ramon, has also joined Kadima, as has former Shas MK David Tal. Kadima is talking to two more Labour MKs, two Shinui MKs, and at least one more Likud MK. There will certainly be a lot of prominent Israeli politicians in the new party.
It is going to be an interesting election.
