Shimon Peres's Prime Ministerial Chances Impove

JERUSALEM, ISRAEL, FEBRUARY 19: Eli Yishai, (C) head of the ultra-Orthodox Shas party, arrives for a meeting with President Shimon Peres to advise the veteran Israeli politician on his choice to head a new coalition government February 19, 2009 in Jerusalem. If neither Likud's Benjamin Netanyahu nor Kadima's Tzipi Livni have enough support to form a coalition government, it is possible that Peres may try and persuade the two to form a national-unity government with each serving as Prime Minister for half a term.
