Four candidates vie to succeed Israeli PM Olmert as Kadima party leader.
A former spy, a former army general, a former mayor and the former head of a secret law enforcement agency are the four candidates to take over the leadership of Israel's Kadima party. The winner of the contest will attempt to form a new Israeli government. Incumbent party leader and prime minister, Ehud Olmert is standing down following growing pressure over multiple corruption investigations during his less than three years in office.SOUNDBITE: Amotz Asa-El, Senior Columnist for the Jerusalem Post
