Rahm Emanuel flirts with Democratic run for the White House

While Democrats search for a new party leader, one old name keeps coming up in conversation: Rahm Emanuel. 

The Democrat has been an investment banker, congressman, White House chief of staff, Chicago mayor, and U.S. ambassador to Japan, and now he's been thinking about adding another title to his long resume: president.

There's just one problem: “As well-known as he is, people don't really know him,” said former Rep. Steve Israel (D-N.Y.), who is in touch with his former House colleague.
