Washington, Sep. 2 : US President Barack Obama''s overall approval rating has only dipped a couple percentage points in August.

In the latest CBS News poll released Tuesday night, the president''s overall approval rating is 56 percent, which is down two points from the last poll taken at the end of July.

That rating for Obama is the lowest in a CBS News poll since he took office in January, but only by one point. The president''s approval rating in mid-July was at 57 percent, according to CBS News polling.

The president''s approval rating hit a high in late April at 68 percent just as Obama was completing his first 100 days in office. The rating remained in the 60s until dropping in that mid-July poll. (ANI)
