The poll of Gaza residents shows a backlash. Hamas got only 23 percent support, down from 29 percent in the previous survey last month, while Fatah climbed from 31 percent to 43 percent.
The poll, the first major survey since the Hamas takeover, also showed that 66 percent of Hamas supporters said they would vote Fatah if it undertook reforms.
The poll, released by Near East Consulting, interviewed 450 residents of the Gaza Strip. It quoted a margin of error of 3.05 percentage points.
