Pollster Khalil Shikaki of the Palestinian Centre for Policy and Survey also reported what he called "the highest number ever recorded" -- 50 percent -- of Palestinians in the impoverished and isolated Gaza Strip considering emigration.
"There's a very high level of frustration we are seeing in Gaza more than at any other time in the past year," Shikaki told reporters by teleconference from the West Bank, referring to results of the June 4-6 survey.
Rebuilding has been slow in Gaza since the 2014 war, in which Palestinian militants launched thousands of rockets and mortar bombs at Israel while Israeli air strikes and artillery battered Gaza, a small densely populated enclave. More than 2,100 Palestinians, mainly civilians, were killed while 67 soldiers and six civilians were killed on the Israeli side.
In the West Bank, where the Fatah party of Palestinian President Mahmoud Abbas exercises self-rule alongside Israeli settlements in occupied territory, support for Hamas has risen to 32 percent from 27 percent three months ago. Fatah weighed in at 36 percent backing, down from 41 percent in March.
Shikaki said Hamas's rising appeal in the West Bank could be attributed in part to frustration with a prolonged impasse in diplomacy between Abbas and Israel on a Palestinian state in territory Israel captured in a 1967 war.Hamas triumphed in the last Palestinian parliamentary election held in 2006. Fresh elections have been repeatedly postponed since Hamas's seizure of power from Fatah in Gaza in a brief 2007 civil war.
