USA Today has an astonishing interactive graph showing Gallop’s polling on presidential approval ratings since Harry Truman assumed the presidency on April 12, 1945, until today. I don’t think I have ever seen so much easily accessible information packed into so small a space. It’s huge fun to play with, as well as being immensely informative. Among the details that pop up:

At this point in his presidency, where does Barack Obama rank among the 12 post–World War II presidents? Tenth.

Who has the lowest approval rating? Harry Truman, at 22 percent in February 1952. (Richard Nixon was at 24 percent when he resigned.)

Who has the highest approval rating? George W. Bush, at 90 percent right after 9/11.

Who has the second highest? George H.W. Bush, at 89 percent after the success of the Gulf War.

What was Bill Clinton’s low point? 37 percent, in June 1993. He never fell below 50 percent after January 1996 and reached his high point (77 percent) in December 1998, just after he had been impeached.

Who had the most consistent approval ratings? Dwight Eisenhower, who only twice, and very briefly, dipped below 50 percent. His peak was right after his re-election in 1956, at 79 percent.
