Reuters reports: Prime Minister Benjamin Netanyahu called on Monday for a snap leadership vote in his Likud party, a contest he is expected to win and which could pave the way for an early national election in Israel.

Some commentators said Netanyahu was quietly preparing for the possibility that President Barack Obama, with whom he has had a testy relationship, will win a second and final term in November, a year before Israel’s currently scheduled ballot.

Freed of campaigning interests if he wins, the Democratic president could redouble pressure on the rightist premier to accommodate the Palestinians in peacemaking, deepening political division in Israel to the Likud’s detriment, analysts predict.

“I wish to announce that I will request elections on January 31 for the leadership of the Likud and its candidate for prime minister,” Netanyahu told Likud legislators at the open part of their weekly meeting in parliament.

“I want to have it now, not only to save good money for the party, but also to avoid internal anguish, so that we, as the leading party, can grapple with the issues that stand before us,” he said.

Netanyahu loyalists said that by holding the leadership ballot on January 31, the party could cut costs by piggybacking on a vote set for its local lists on that date. The Likud charter requires party leadership votes to take place at least six months before national elections.

“Let’s be honest, no one really thinks that the prime minister, who is really, at the end of the day, running things well, and has wall-to-wall support in the Likud, will not be elected,” said Environment Minister Gilad Erdan of the Likud, whose central committee must be convened to authorize the date.

Hanan Krystal, Israel Radio’s political analyst, said Netanyahu might also opt to bring forward the next Israeli general election, due in November 2013, should Obama look likely to beat Republican rivals in the U.S. ballot.

Resented among Jewish and conservative Christian voters over his handling of the Netanyahu government, Obama last week promoted his administration’s efforts to secure Israel from foes like Iran.

“At the highest echelons, they have long been saying that if Obama is elected for a second term, the carrot will be replaced by a stick,” Krystal said.
