President Barack Obama's approval poll ratings fall

It has been an extraordinary first year for President Barack Obama, during which unemployment has hit 26-year highs, two of the biggest US carmakers have declared bankruptcy, and the president has pushed his healthcare bill and won a Nobel Peace Prize.

His approval ratings have fallen from highs of about 68% in his first weeks in the job to about 50%.

Look at the graph below to see how his popularity has changed in his first year in charge.

The approval ratings were calculated by Gallup, Pew and ABC/Washington Post and collated by www.pollster.com   where you can find full data from these and other polls.
