Bush's reputation might be ready for immage building

Former U.S presidents Bush might be image building in this time. the 63-year-old Bush has been keeping a low profile, fading from view as the country turned its attention to his successor, President Barack Obama.

Events might be turning in Bush's favor just as he and his family emerge to tell their side of the story, first with the release this week of Laura Bush's memoir, "Spoken From the Heart," then in November release of his book, "Decision Points."

April 2008 surveyed, while he was still in office, 61 percent of historians said that Bush was the worst president in U.S. history, according to the History News Network at George Mason University in Virginia .

Historians also say that it can be decades before they can analyze a president's impact objectively, time for policies to take hold, for details of internal debates to become known and for partisans on both sides to leave the stage.
