Tel Aviv - Israel's ruling Kadima party began electing a new leader Wednesday to replace discredited Prime Minister Ehud Olmert.
Some 144 polling stations opened their doors at 10 am (0700 GMT) at locations throughout the country. They will stay open for 12 hours. "I call on everyone to come and vote," frontrunner Tzipi Livni told reporters as she cast her ballot in Tel Aviv.
Livni, 50, Israel's foreign minister and chief negotiator in talks with the Palestinians, has had a consistent, two-digit lead in opinion polls over her main rival, Transport Minister Shaul Mofaz.
But Mofaz, 60, has expressed confidence he will take the contest because he has greater influence with field activists who plan to bring in undecided voters.
