Obama finished with lower average approval rating than Bush or Nixon

That puts him behind Richard Nixon, who resigned, and George W. Bush, who saw his approval rating drop as low as 25 percent near the end of his term.

It puts him ahead of only Gerald Ford (47.2 percent), Jimmy Carter (45.5 percent) and Harry Truman (45.4 percent).

Gallup, in an analysis released Friday, published the average approval rating for all twelve presidents who have served since World War II.
