Why the Labor party split

Caroline Glick explains why the Labor party split this week. According to Haaretz and to Labor leaders who opposed Barak, the end of the line for Barak came early this month with Haaretz's publication of a report claiming that the Obama administration had soured on Barak due to his failure to convince Netanyahu to extend the Jewish construction ban in Judea and Samaria for an additional 90 days.
