The first potential candidate ready to challenge Prime Minister Benjamin Netanyahu for the Likud leadership came forward Sunday night.Beersheba Physicist Vladimir Herczberg, who has run against Netanyahu in the past, said he wants to face off against him again.But Herczberg said he had conditions for running: He is not ready to pay the Likud the NIS 10,000 registration fee, nor is he ready to submit signatures from 500 Likud members, which are also required to run.Herczberg, 70, said he hoped readers of The Jerusalem Post would donate the money to him."I don't want to take money away from my family," he said. "But I have energy. I still have a good head. I am ready to go for it."Herczberg said that ahead of the 2012 Likud primary, a Canadian businessman contributed money to cover the registration fee, but the Likud did not permit him to run, because he did not submit the required signature."I don't want to run around and get people to sign a piece of paper," Herczberg said. "I am too old for that. I am not a small child."Likud central committee chairman Haim Katz said the Likud could save hundreds of thousands of shekels if no one runs against Netanyahu and a leadership race is avoided. No one has expressed willingness to run until Herczberg.Herczberg said that if elected leader of Likud, he would end the current wave of Arab violence and expel from Israel anyone who thinks Israel is occupying Palestinian land. He said he would start by expelling Meretz leader Zehava Gal-On and Zionist Union MK Tzipi Livni."I have a platform, and unlike Netanyahu, I know how to bring order around here. he said.
