When asked which president has done the best job in their lifetimes, more Americans name Barack Obama than any other president. More than four-in-ten (44%) say Obama is the best or second best president of their lifetimes, compared with about a third who mention Bill Clinton (33%) or Ronald Reagan (32%).

Not yet halfway through his term, 19% say Donald Trump has done the best or second best job of any president of their lifetimes. That is comparable with the share who viewed Obama as one of the best presidents in 2011 (20%).

The survey by Pew Research Center, conducted June 5-12 among 2,002 adults, asks people in an open-ended format which president has done the best job in their lifetimes. The analysis is based on their first and second choices.
