"So even as Obama seeks to define what his presidency meant for America, his legacy remains in question."

Whatever Obama's legacy ends up, I very seriously hope it doesn't include any negative image as was the Clintons after they moved out of the WH. The Clintons stole all kinds of gifts and property given to the United States by other countries and world leaders. The Clintons were forced to return items to the WH and in some cases forced to pay for them.  I note as of a few days past Hillary is being investigated now for the removal of gifts and property given to the United States, State Department office, which are reportedly in their New York home. Pretty embarrassing for the United States to have a former President and first lady caught red handed thieving.  Good Grief !
I didn't care for Obamas policies, but I believe he and Michelle surely have more class then the Clintons.
