Likud party members continued voting past the extended 1 a.m. deadline due to long lines after computer problems forced the deadline to moved back from 11 p.m. Results are expected shortly after 2:30 a.m.

The voter turnout was slightly less than 50 percent.

By 7:45 pm, only 33 percent of Likud members had cast their votes. A low turnout would help Moshe Feiglin, head of the Jewish Leadership faction, as his supporters are widely considered more determined to vote. Likud head Binyamin Netanyahu has publicly criticized Feiglin on several occasions, and claims that if Feiglin wins a top slot on the Likud list, the party will lose seats in the national elections.

Some Likud officials called to hold the primary vote on Tuesday as well to allow for higher turnout.

Feiglin's supporters rejected calls from within the Likud to continue voting. “In light of Netanyahu's supporters' hysterical behavior and the unending attempts to undermine Feiglin's candidates, there's reason to fear the results would be tampered with if the computers were left under their supervision overnight,” Feiglin aides said.

Likud is not the first party to have difficulties with computerized voting: Last week, the Labor primaries were canceled after voting had begun on Tuesday when the party's new computerized voting system caused serious delays and left thousands unable to vote. The party moved its primaries to Thursday and held the second round of voting using the more traditional method of placing paper slips in envelopes.
