Washington (CNN) The latest CNN/ORC Poll found warning signs for former Florida Gov. Jeb Bush, but for his brother, former President George W. Bush, the poll reveals some happier news: For the first time in a decade, more Americans say they like him than dislike him.

According to the poll, 52% of adults had a favorable impression of George W. Bush, 43% unfavorable. When Bush left office in 2009, only about a third of Americans said they had a positive opinion of him. In a February 2009 poll conducted about a month after he left office, Republicans were the only group among which a majority said they had a favorable view of Bush. Even among self-described conservatives, only 50% had a favorable take on the former president and champion of "compassionate conservatism."

Bush's overall favorability has remained well below 50% for much of his time as a presidential alum. This new poll presents a notable shift.

As of a year ago, 46% had a favorable take on the former president, 51% an unfavorable one. Since then, Bush has gained in esteem among men (up 11 points), Republicans (up 10 points), those with household incomes under $50,000 (up 10 points), younger adults (up 9 points among those under age 50) and suburbanites (up 8 points).
