Barack Obama might have been in office for less than a week, but the euphoria is beginning to wane.
The new President's approval ratings have fallen from a stratospheric 83 per cent to a more modest - although still impressive - 68 per cent.
Washington analysts said the scale of the drop in the Gallup poll underlines the immense challenges Mr Obama faces in trying to turn round the U.S.'s battered fortunes.
He still remains vastly more popular than his predecessor George Bush - who left office with around 25 per cent approval.
