Ex-defence chief Shaul Mofaz (L) holds his ballot for the Kadima party primary election before casting it at a polling station in the central town of Kfar Saba March 27, 2012. Opinion polls predicted a close race between Tzipi Livni, Israel's former foreign minister, and Mofaz among Kadima's 100,000 eligible voters charged with choosing a candidate to challenge Prime Minister Benjamin Netanyahu in a national poll expected by next year.
