Query: The best way to understand Obama.

Most audio books are read aloud by actors. This audio book is read aloud by the author, Barack Obama. Obama has a pleasant speaking voice. The end result is that the listener has a golden opportunity to hear this major political figure talk about personal life, economics, race relations, education opportunity and -- oh yes -- politics. Don't miss this opportunity.Glenn Rennels
