A new Gallup poll shows that the number of people who have a favorable impression of Barack Obama has fallen to its lowest point since he became president. Fifty-six percent say they have a favorable impression of Obama, versus 40 percent who say they have an unfavorable impression. (Four percent say they have no opinion.)

That’s a big change from the height of the battle for the Democratic nomination last year; in February 2008, just 48 percent had a favorable impression of Mrs. Clinton, versus 49 percent who had an unfavorable impression.
