PRINCETON, NJ -- Of the nine U.S. presidents who have served in the past 50 years, John F. Kennedy continues to earn the highest retrospective job approval rating from Americans, now 85%. Ronald Reagan ranks second, with 74%. While these presidents' ratings are largely unchanged from 2006, Bill Clinton's rating has improved, putting him in third place, while Jimmy Carter, at 52%, has dropped from third to sixth. Richard Nixon remains the lowest rated.
http://www.gallup.com/poll/145064/Kennedy-Highest-Rated-Modern-President-Nixon-Lowest.aspxThis is Gallup's first retrospective approval measure of George W. Bush since he left office in 2009. His 47% approval and 51% disapproval rating puts him in Nixon's company as the only two presidents whose retrospective disapproval exceeds their approval, although the balance is much more negative for Nixon: 29% approve and 65% disapprove.
For Bush -- whose job approval ratings as president descended into the 20s in his final year -- a 47% retrospective approval is actually relatively positive, as his approval rating as president last reached that level in 2005.
