Carter, who served in the White House from 1977 to 1981, ranks first among the four surviving presidents. George W. Bush, who has only been out of office seven months, comes in last with nine percent (9%) support.

Bill Clinton, president from 1993 to 2001, made headlines again last week when he successfully brought two imprisoned U.S. women reporters home from North Korea. He is viewed by 29% as the ex-president who has performed best since stepping down as chief executive.
