Barack Obama [Images], who took charge as the 44th President of the United States on January 20 amid sky high approval ratings, is already facing a decline in his tremendous popularity.

A recently conducted poll shows that Obama's job approval ratings have dipped due to the relentless financial crisis and the government's stumbling stimulus packages to revive the American economy.

The poll, conducted by the CNN and Opinion Research Corporation survey between February 18 and 19, shows that Obama's approval ratings have dipped by nine per cent in the last one month.

Obama, who won the presidential race after his campaign promised to bring several positive changes, had entered the White House with an approval rating of 77 per cent.

But the poll revealed that only 67 per cent Americans approved of Obama now. As many as 23 per cent of people felt that the country's first African American President had fallen short of expectations.
