Bernanke gets top grade in investor poll

The nation's top monetary official has received high marks in a new investor survey.

Federal Reserve Chairman Ben Bernanke received the highest rating for handling the worst financial crisis since the Great Depression, according to the first Quarterly Bloomberg Global Poll.

In the survey, 75 percent of respondents had a favorable view of Bernanke, and believed that the 55-year-old chairman should be re-appointed to another four-year term as head of the world's most powerful central bank when his current one expires in January.
