Supporters of Israeli Foreign Minister and candidate for Kadima party leadership Tzipi Livini react as they hear the exit polls in Tel Aviv, Wednesday, Sept. 17, 2008. TV exit polls say Livni has won a clear victory in the party primary election to replace Prime Minister Ehud Olmert.

Foreign Minister Tzipi Livni won a clear victory in the Kadima Party’s primary election Wednesday, TV exit polls showed, placing her in a good position to become Israel’s first female leader in 34 years and sending a message that peace talks with the Palestinians will proceed.

Cheers and applause broke out at party headquarters when Israel’s three TV networks announced their exit polls giving Livni between 47 percent and 49 percent, compared with 37 percent for her closest rival, former defense minister and military chief Shaul Mofaz. Livni supporters hugged each other and shed tears of joy.

Livni needed 40 percent of the vote to avoid a runoff next week.

If official results bear out the exit polls, as is likely, the 50-year-old Livni will replace Prime Minister Ehud Olmert as head of Kadima. Olmert, the target of a career-ending corruption probe, had promised to step down as soon as a new Kadima leader was chosen.

Livni was expected to address party activists Thursday, after vote counting was completed. Late Wednesday she thanked her supporters in a phone call to her headquarters.

“You fought like lions … you did an amazing thing, and I just want to do all the things you fought for,” she said. “I know you did it as friends, but, like me, you did it because you want this to be a better place.”

Livni will have 42 days to form a new ruling coalition. If she succeeds, she will become Israel’s first female prime minister since Golda Meir. If she fails, the country will then hold elections in early 2009, a year and a half ahead of schedule. Olmert will remain as a caretaker leader until a new coalition is approved by parliament.

Nationally, polls show Livni roughly tied with Benjamin Netanyahu of the hard-line Likud Party. A new nationwide vote would likely turn into a referendum on the current effort to forge a historic peace deal with the Palestinians.

Foreign minister since 2006, Livni is Israel’s lead negotiator in the peace talks. She is a rare female power figure in a nation dominated by macho military men and a religious establishment with strict views on the role of women. A former lawyer, army captain and one-time agent in the Mossad spy agency, Livni favors diplomacy over confrontation, even though she said last week that she has “no problem pulling the trigger when necessary.”

A victory by Mofaz would have raised serious questions about Israel’s involvement in peace talks with both the Palestinians and Syria. His approach is seen as far less conciliatory than hers. Had he won, the Iranian-born politician could have become Israel’s first prime minister of Middle Eastern, or Sephardic, descent.

Two other candidates, Cabinet minister Meir Sheetrit and former Shin Bet security service director Avi Dichter lagged far behind in the polls.

Joyce Amiel, a Kadima supporter in Tel Aviv, said she was voting for Livni “mainly because she is a woman, even though her positions are not clear. We think she would do the best job. We want her to win.”

Casting her vote in Tel Aviv, the usually reserved Livni bubbled with uncharacteristic enthusiasm. She said she was pleased with the turnout at her polling station and urged people to vote.

“You can determine today what the character of Kadima will be,” Livni said. “You can determine today if you really have had enough of old-time politics. Come and vote, bring your children, and show them how you are changing the country.”

Palestinian Information Minister Riad Malki was hopeful that peace talks could succeed under Israel’s new leadership.

“We welcome the results of the election, and we are going to deal with any new prime minister in Israel,” he told The Associated Press. “We hope this new prime minister will be ready to … reach a peace deal with the Palestinians that ends the occupation and allows the establishment of an independent Palestinian state living beside Israel.”

Kadima extended voting by a half-hour Wednesday night, apparently to give voters returning from work more time to cast their ballots.

Israeli media reported that about 55 percent of the 74,000 party members cast ballots, with a crush of voters as the deadline approached.

The primary was Kadima’s first since the party was founded by then-Prime Minister Ariel Sharon in 2005. Sharon suffered a debilitating stroke in early 2006, and Olmert subsequently led the party to victory in elections.

Olmert is under police investigation over his financial dealings. But he has been pursuing peace talks with the Palestinians and has pledged to continue as long as he is in office.

However, both he and his Palestinian counterparts now say they are unlikely to reach the U.S.-set target date of year’s end for a final peace deal. Also, any agreement they might reach would not be implemented until Abbas regains control of the Gaza Strip, overrun by Islamic Hamas militants in June 2007.

Israeli political science professor Gadi Wolfsfeld predicted Livni could use a peace deal to win a national election.

“If she comes to a tentative agreement with the Palestinians, why not run on that platform, which would be very good for her?” he said. AP
