Which is six points higher than Obama.

Via Gallup:

Americans view each of the four former living presidents more positively than negatively, while giving Bill Clinton and George H.W. Bush higher favorable ratings than George W. Bush and Jimmy Carter. Current President Barack Obama has a net-negative favorable rating.

The younger Bush’s current favorable rating is likely lower than other former presidents’ ratings because his term, marked by job approval ratings well below 40% during his final two years in office, is the freshest in Americans’ minds.

Though Carter left office with similarly poor job approval ratings, his lower favorable ratings today are mostly attributable to one in six Americans not having an opinion of him. That includes 36% of those younger than 30, all of whom were born after Carter left office in 1981. The only other time Gallup measured opinions of Carter with this question format, in 2007, 69% rated him favorably, 27% unfavorably, and 4% had no opinion. […]

George W. Bush appears to be reaping the public opinion benefits of being a former president. His current 53% favorable rating marks the first time it has been above the majority level since 2005, early in his second term as president.
