President Barack Obama says his low approval rating is a reflection of public unhappiness with Congress.

Obama tells CBS in an interview broadcast Sunday that he's "impacted," just like Congress, when people aren't happy with Washington.

He says he understands that his arguments that the country would have been worse off if he hadn't taken certain actions don't resonate with the millions of unemployed people.

The president, who's vacationing on Martha's Vineyard, Mass., says he expects to be judged in November 2012 on whether things have improved.

Recent public opinion polls have shown Obama's job approval rating at near 40 percent, the lowest of his presidency.

Obama taped the CBS' `Sunday Morning" interview last Wednesday in Illinois at the end of a Midwest bus tour focused on the economy.
