Barack Obama has slid in the latest Newsweek poll, after absorbing the hard hits of his Pennsylvania loss and the controversies over his “bitter” remark and efforts by his opponents to keep alive the issue of his association with Rev. Jeremiah Wright.

Obama still leads Hillary Clinton 46 percent to 38 percent in the survey conducted April 24-25. The margin of error is 5 percent for Democrats who were polled. A week ago, in a report headlined “Hillary Drops Back,” the Newsweek poll had Obama ahead 54 percent to 35 percent. On the question of who was more electable, Obama had a 55 percent to 33 percent lead a week ago, but now his edge over Clinton is 46 percent to 38 percent.

Newsweek says that now 4 in 10 of registered voters, including Republicans and independents, now have an unfavorable opinion of him and the same number say they would not vote for him in the general election. About the same number of voters say their opinion is less favorable because of the Wright controversy and the “bitter” remark. That being said, both Obama and Clinton hold narrow leads over John McCain, although both are within the poll’s margin of error. Fifty-three percent of voters have a favorable opinion of Obama, compared to 51 percent for McCain and 47 percent for Clinton. The margin of error for all voters is 3 percent.
