This news should be extremely concerning for the Prime Minister. MK Danny Danon and MK Tzipi Hotovely are far right to be sure, but they don't come close to the radicalism of Lieberman or Shas. Both are young, energetic, eloquent MKS respected by a large plurality of Israeli voters and enjoy relations with American political figures. This plurality may not be the median voter but it certainly is the party base. This move isolates Netanyahu from those who elected him, and weakens his control of the Knesset.
