With about 20 percent of the ballots cast Wednesday counted, Israeli media said Netanyahu had won the support of about 75 percent of electors, giving him an unassailable lead over challenger Danny Danon, a former deputy defense minister.
Some 100,000 Likud members were eligible to vote in the poll. Netanyahu was the heavily favored candidate in the vote.
Early opinion polls ahead of the March 17 general elections show Netanyahu’s Likud party in a neck-and-neck race with a joint list headed by Labor Party leader Isaac Herzog and former Justice Minister Tzipi Livni of the Hatnuah party.
Netanyahu has been Israeli prime minister since 2009, taking a hard-line in Israel’s relations with the Palestinians. He has cultivated members of his right-wing coalition through supporting contentious legislation that would enshrine into law Israel’s status as a Jewish state.
But he has so far drawn a line with the right at efforts to change the status at a disputed Jerusalem holy site by allowing Jews to pray there, fearing that such a change would solidify anti-Israeli opinion in the Islamic world and undermine the country’s relations with the United States and Europe.
Early returns in the Likud primary suggest that one major backer of the change in the status quo at the site, known to Jews as the Temple Mount and Muslims as the Nobel Sanctuary, did not win enough support to gain a chance to return to parliament, while another supporter of that change did.
