Only once in all of Israel’s history has a new centrist party managed to win an election and form a government. It happened in 2006, when Kadima under Ehud Olmert won 29 seats. But Olmert waged his campaign from the position of prime minister after replacing Ariel Sharon, who fell into a coma in the heat of the election campaign.
Kadima’s big advantage was that it rose from within the government as a result of the crisis in the Likud caused by Sharon’s plan to disengage from Gaza. Furthermore, it already had infrastructure based on mayors and local authorities who had defected from the Likud. At its peak, polls gave Kadima as many as 40 seats. The leadership it presented to the public consisted of the most senior figures from the right and the left, with sweeping experience in government. They included peace icon late President Shimon Peres, architect of the Oslo Accords, and many ministers from the Likud and Labor parties.
