After months of bickering Degel Hatorah and Aguda agreed to run to together again. They expect to get 6 seats (1 more then last time) and they will rotate the 6th seat between Degal and Aguda. On a related front, the Dati Leumi parties also united and the NRP and the Ichud Haleumi will run together.
It will be interesting to see how things shake out. I believe that Olmert is starting to run into trouble with Amona, Hamas winning the PA election and his interview where he said that there will be more disengagements. I don't believe the polls and think that the election will be much closer then it appears now.
