In the Jerusalem Post headline, Palestinians split on Itamar, the statistics cited in the article say that approximately two-thirds of the Palestinians who were polled opposed the attack (Itamar is the name of an Israeli town in the West Bank that was the site of a terrorist attack).
Can split mean divided in a manner other than 50/50?
When contacted, the Jerusalem Post editorial staff defended the headline. Do you agree? If so, is there a limit to the ratio; for instance, if 90% were opposed, would it still be called split?
