According to a poll taken by the Dahaf Institute for the Knesset Channel, 77 percent of Israelis are dissatisfied with Olmert's performance as prime minister. Forty seven percent of the 420 respondents asked to grade Olmert on his performance gave the prime minister a grade of "very poor," 30% gave him a grade of "fairly bad," and 20% graded him as "good." Only one percent of those asked said they think Olmert's performance has been "very good." In addition, 69% of the survey participants said the prime minister's lacked leadership skills, and 60% have a low opinion of his integrity. To the question, "How would you rate Olmert's resilience under pressure?" 62% of the respondents said he does not deal well with pressure, while 37% believe Olmert deals well under pressure. When asked what would change their opinion of the prime minister, 45% said their appreciation would increase if he would remove Defense Minister Amir Peretz from his post. Only four percent said they would not appreciate such a move. Fifty-one percent of the respondents said Peretz's dismissal would not affect their judgment of the prime minister. Twenty percent said they would like Olmert to dismiss IDF Chief of Staff Dan Halutz, as opposed to six percent of participants who said firing the army chief would decrease their appreciation for the PM.
