Neshama, Don't you know the saying: "Divide and conquer?" This change will not bode well for Barak, nor for Labor and also not for Kadima. Barak will bring with him much of what remains of the centrist Labor faction. The rest of them are already in Kadima. This will push labor to take a more left wing position than before, which will in turn push Meretz to be even more left wing then they already are. In next elections, the chances are that the Kadima - Labor - New Comfy Seat Barak party - Meretz groups will all be fighting for the same group of voters. Likud on the other hand stands to gain.
